This article deals with the definitions of a 'month' that are mainly of significance in astronomy. For other definitions, including a description of a month in the calendars of different cultures around the world, see: month.
In Shona, Middle-Eastern, and European traditions, the month starts when the young crescent moon first becomes visible, at evening, after conjunction with the Sun one or two days before that evening (e.g., in the Islamic calendar). In ancient Egypt the lunar month began on the day when the waning moon could no longer be seen just before sunrise. Others run from full moon to full moon.
Yet others use calculation, of varying degrees of sophistication, e.g., the Hebrew calendar or the ecclesiastical lunar calendar. Calendars count integer days, so months may be 29 or 30 days in length, in some regular or irregular sequence. Lunar cycles are prominent, and calculated with great precision, in the ancient Hindu 'Panchang' Calendar, widely used in the Indian sub continent. In India the month from conjunction to conjunction is divided into thirty parts known as tithis. A tithi is between 19 to 26 hours long. The date is named after the tithi ruling at sunrise. When the tithi is shorter than the day, the tithi may jump. This case is called xaya or loap. Conversely a tithi may 'stall' as well, that is - the same tithi is associated with two consecutive days. This is known as vriddhi.
In English common law, a "lunar month" traditionally meant exactly 28 days or four weeks, thus a contract for 12 months ran for exactly 48 weeks. In the United Kingdom, the lunar month was formally replaced by the calendar month for deeds and other written contracts by the Law of Property Act 1925 and for all other legal purposes by the Interpretation Act 1978.
Most of the following types of lunar month, except the distinction between the sidereal and tropical months, were first recognized in Babylonian lunar astronomy.
The period of the Moon's orbit as defined with respect to the celestial sphere of apparently fixed stars (the International Celestial Reference Frame (ICRF)) is known as a sidereal month because it is the time it takes the Moon to return to a similar position among the stars (Latin: sidera): 27.321661 days (27 d 7 h 43 min 11.6 s). This type of month has been observed among cultures in the Middle East, India, and China in the following way: they divided the sky into 27 or 28 lunar mansions, one for each day of the month, identified by the prominent star(s) in them.
The synodic month (Greek: συνοδικός, synodikós, meaning "pertaining to a synod, i.e., a meeting"; in this case, of the Sun and the Moon) is the average period of the Moon's orbit with respect to the line joining the Sun and Earth. This is the period of the lunar phases, because the Moon's appearance depends on the position of the Moon with respect to the Sun as seen from the Earth.
While the Moon is orbiting the Earth, the Earth is progressing in its orbit around the Sun. After completing a sidereal month, the Moon must move a little further to reach the new position having the same angular distance from the Sun, appearing to move with respect to the stars since the previous month. Therefore, the synodic month takes 2.2 days longer than the sidereal month. Thus, about 13.37 sidereal months, but about 12.37 synodic months, occur in a Gregorian year.
Since Earth's orbit around the Sun is elliptical and not circular, the speed of Earth's progression around the Sun varies during the year. Thus, the angular rate is faster nearer periapsis and slower near apoapsis. The same is so for the Moon's orbit around the Earth. Because of these variations in angular rate, the actual time between lunations may vary from about 29.18 to about 29.93 days. The long-term average duration is 29.530587981 days (29 d 12 h 44 min 2.8016 s). The synodic month is used to calculate eclipse cycles.
It is customary to specify positions of celestial bodies with respect to the vernal equinox. Because of Earth's precession of the equinoxes, this point moves back slowly along the ecliptic. Therefore, it takes the Moon less time to return to an ecliptic longitude of 0° than to the same point amid the fixed stars: 27.321582 days (27 d 7 h 43 min 4.7 s). This slightly shorter period is known as the tropical month; compare the analogous tropical year.
The Moon's orbit approximates an ellipse rather than a circle. However, the orientation (as well as the shape) of this orbit is not fixed. In particular, the position of the extreme points (the line of the apsides: perigee and apogee), rotates once (apsidal precession) in about 3,233 days (8.85 years). It takes the Moon longer to return to the same apsis because it has moved ahead during one revolution. This longer period is called the anomalistic month and has an average length of 27.554551 days (27 d 13 h 18 min 33.2 s). The apparent diameter of the Moon varies with this period, so this type has some relevance for the prediction of eclipses (see Saros), whose extent, duration, and appearance (whether total or annular) depend on the exact apparent diameter of the Moon. The apparent diameter of the full moon varies with the full moon cycle, which is the beat period of the synodic and anomalistic month, as well as the period after which the apsides point to the Sun again.
An anomalistic month is longer than a sidereal month because the perigee moves in the same direction as the Moon is orbiting the Earth, one revolution in nine years. Therefore, the Moon takes a little longer to return to perigee than to return to the same star.
A draconic or draconitic month is also known as a nodal or nodical month. The name draconic refers to a mythical dragon, said to live in the lunar nodes and eat the Sun or Moon during an eclipse. A solar or lunar eclipse is possible only when the Moon is at or near either of the two points where its orbit crosses the ecliptic plane; i.e., the satellite is at or near either of its orbital nodes.
The orbit of the Moon lies in a plane that is inclined about 5.14° with respect to the ecliptic plane. The line of intersection of these planes passes through the two points at which the Moon's orbit crosses the ecliptic plane: the ascending node, where the Moon enters the Northern Celestial Hemisphere, and the descending node, where the Moon moves into the Southern.
The draconic or nodical month is the average interval between two successive transits of the Moon through the same node. Because of the torque exerted by the Sun's gravity on the angular momentum of the Earth–Moon system, the plane of the Moon's orbit gradually rotates westward, which means the nodes gradually rotate around Earth. As a result, the time it takes the Moon to return to the same node is shorter than a sidereal month, lasting 27.212220 days (27 d 5 h 5 min 35.8 s). The nodes of the Moon's orbit precesses 360° in about 6,798 days (18.6 years).
A draconic month is shorter than a sidereal month because the nodes precess in the opposite direction to that in which the Moon is orbiting Earth, one rotation every 18.6 years. Therefore, the Moon returns to the same node slightly earlier than it returns to meet the same reference star.
Regardless of the culture, all lunar months approximate the mean length of the synodic month, the average period the Moon takes to cycle through its phases (new, first quarter, full, last quarter) and back again: 29–30 days. The Moon completes one orbit around Earth every 27.3 days (a sidereal month), but due to Earth's orbital motion around the Sun, the Moon does not yet finish a synodic cycle until it has reached the point in its orbit where the Sun is in the same relative position.
|Month type||Length in days|
|anomalistic||27.554549878 − 0.000000010390 × Y|
|sidereal||27.321661547 + 0.000000001857 × Y|
|tropical||27.321582241 + 0.000000001506 × Y|
|draconic||27.212220817 + 0.000000003833 × Y|
|synodic||29.530588853 + 0.000000002162 × Y|
Note: In this table, time is expressed in Ephemeris Time (more precisely Terrestrial Time) with days of 86,400 SI seconds. Y is years since the epoch (2000), expressed in Julian years of 365.25 days. For calendric calculations, one would probably use days measured in the time scale of Universal Time, which follows the somewhat unpredictable rotation of the Earth, and progressively accumulates a difference with ephemeris time called ΔT.
Apart from the long term (millennial) drift in these values, all these periods vary continually around their mean values because of the complex orbital effects of the Sun and planets affecting its motion.
In medieval times, the part of the Moon's orbit south of the ecliptic was known as the 'dragon' (which devoured the Moon during eclipses) and from this we get the terminology 'dragon's head' for the ascending node and 'dragon's tail' for the descending node. … The periods between successive nodes has, over time, been termed the dracontic, draconic and draconitic month, the words deriving from the Greek for 'dragon'.
The nodical month is the time in which the Moon accomplishes a revolution with respect to her nodes, the line of which is also movable.
This is a list of holidays celebrated within the Buddhist tradition.
Vesak: Buddha's birthday is known as Vesak and is one of the major festivals of the year. It is celebrated on the first full moon day in May, or the fourth lunar month which usually occurs in May or during a lunar leap year, June. In some countries this has become an occasion to not only celebrate the birth but also the enlightenment and parinirvana of the Buddha.
Parinirvana Day: also known as Nirvana Day, a Mahayana Buddhist holiday celebrated in East Asia, usually on February 15.
Magha Puja: Magha Puja is an important religious festival celebrated by Buddhists in Thailand, Cambodia, and Laos on the full moon day of the third lunar month (this usually falls in February or March)
Buddha's Birthday: Also known as "Hanamatsuri" it is celebrated April 8 and in Japan baby Buddha figurines are ceremonially washed with tea.
Asalha Puja Day: Also known as "Dharma Day" celebrates the Buddha's first teaching on the full moon day of the 8th lunar month, approximately July.
Uposatha: This day is known as observance day, there are four holy days on the new moon, full moon, and quarter moon days every month.
Kathina Ceremony: This robe offering ceremony, is held on any date within the end of the Vassa Retreat. New robes and other requisites can be offered by the laity to the monks.
Abhidhamma Day: According to Burmese tradition, this day celebrates when the Buddha went to the Tushita Heaven to teach his mother the Abhidhamma. It is celebrated on the full moon of the seventh month the Burmese lunar year which starts in April.
Loy Krathong: When the rivers and canals are full of water, this festival takes place in all parts of Thailand on the full moon night of the twelfth lunar month. Bowls made with leaves, candles, and incense sticks, are in the water, and represent bad luck disappearing.
Madhu Purnima: It occurs on the day of the full moon in Bhadro (August/September). The day commemorates an occasion on which the Buddha retreated to the wilderness of Parileyya forest to bring peace between two quarrelling factions of disciples.
The Ploughing Festival: During the half moon in May, two oxen pull a plough painted gold. Following behind them are girls dressed in white scattering rice seeds. This was to celebrate the Buddha's first moment of enlightenment.
The Elephant Festival: The Buddha used an example of a wild elephant which is harnessed to a tame one to be trained. He said that a person who is new to Buddhism should have a special relationship with an older Buddhist. This festival takes place on the third Saturday in November.
The Festival of the Tooth: In Sri Lanka there is a temple that houses a tooth relic of the Buddha. It can't be seen, but once a year there is a procession for it on the full moon in August.
Hungry Ghost Festival: "Ancestor Day" or "Ulambana" is celebrated from the first to the fifteenth days of the eighth lunar month. This is the day when the monastics complete their Rains Retreat. It was considered that many monastics would have made progress during their retreat and therefore become a greater field of merit. Lay devotees make offerings on behalf of their ancestors and dedicate the merit towards those suffering in the preta realm to relieve their suffering.
Avalokitesvara's Birthday: This festival celebrates the Bodhisattva ideal. On the full moon day in March It represents the perfection of compassion in Mahayana traditions of Tibet and China.
Bodhi Day: The holiday which commemorates the day that the historical Buddha experienced enlightenment.Diyu
Diyu (Chinese: 地獄) is the realm of the dead or "hell" in Chinese mythology. It is loosely based on a combination of the Tamil concept of Naraka, traditional Chinese beliefs about the afterlife and a variety of popular expansions and reinterpretations of these two traditions.
Diyu is typically depicted as a subterranean maze with various levels and chambers, to which souls are taken after death to atone for the sins they committed when they were alive. The exact number of levels in Diyu and their associated deities differ between Buddhist and Taoist interpretations. Some speak of three to four "courts"; others mention "Ten Courts of Hell", each of which is ruled by a judge (collectively known as the Ten Yama Kings); other Chinese legends speak of the "Eighteen Levels of Hell". Each court deals with a different aspect of atonement and different punishments; most legends claim that sinners are subjected to gruesome tortures until their "deaths", after which they are restored to their original state for the torture to be repeated.Ecclesiastical new moon
An ecclesiastical new moon is the first day of a lunar month (an ecclesiastical moon) in an ecclesiastical lunar calendar. Such months have a whole number of days, 29 or 30, whereas true synodic months can vary from about 29.27 to 29.83 days in length. Medieval authors equated the ecclesiastical new moon with a new crescent moon, but it is not a phase of the true moon. If the ecclesiastical lunar calendar is accurate, the ecclesiastical new moon can be any day from the day of the astronomical new moon or dark moon to two days later (see table).
The ecclesiastical new moon which falls on or next after March 8 is of special importance, since it is the paschal new moon that begins the paschal lunar month (see table). The fourteenth day of the same lunar month is the first of the calendar year to occur on or next after March 21. This fourteenth day was called the paschal full moon by medieval computists. Easter is the following Sunday.
Calendar pages in medieval liturgical books indicated the ecclesiastical new moons by writing the Golden Number to the left of the day of the month on which the ecclesiastical new moon would occur in the year of that Golden Number. In some places the age of the moon was announced daily in the office of Prime at the reading of the martyrology.
When in the 13th century Roger Bacon complained about the discrepancy between the ecclesiastical moon and the observed lunar phases, he specifically mentioned the discrepancy involving the ecclesiastical new moon
Quilibet computista novit quod fallit primatio per tres dies vel quatuor his temporibus; et quilibet rusticus potest in coelo hunc errorem contemplari. (Any computist knows that the prime [of the moon] is off by three or four days in our time; and any rustic can see this error in the sky.)
These complaints were finally addressed by the construction of the Gregorian calendar.Ekadashi
Ekādaśī (ekāhdaśī, "Eleven"), also spelled as Ekādaśi, is the eleventh lunar day (tithi) of each of the two lunar phases which occur in a Hindu calendar month - the Sukla Paksha (the period of the brightening moon also known as the waxing phase) and the Krishna Paksha (the period of the fading moon also known as the waning phase).In Hinduism and Jainism, Ekādaśī is considered a spiritual day and is usually observed by partial fast. Beans and grains are not consumed by observant people during because they are believed to be contaminated by sin. Instead, only fruit, vegetables, and milk products are eaten. This period of abstinence starts from sunrise on the day of Ekādaśī to sunset on the following day.
Hindu rules state that anyone between the ages of eight years and eighty years should fast, including forgoing water. However, people who are sick, have health issues, or are pregnant are exempt from the rule and may consume light food including milk and fruits.The timing of each Ekādaśī is according to the position of the moon. The Hindu calendar marks progression from a full moon to a new moon as divided into fifteen equal arcs. Each arc measures one lunar day, called a tithi. The time it takes the moon to traverse a particular distance is the length of that lunar day. Ekādaśī refers to the 11th tithi, or lunar day. The eleventh tithi corresponds to a precise phase of the waxing and waning moon. In the bright half of the lunar month, the moon will appear roughly 3/4 full on Ekādaśī, and in the dark half of the lunar month, the moon will be about 3/4 dark on Ekādaśī.
There are usually 24 Ekādaśīs in a calendar year. Occasionally, there are two extra Ekādaśīs that happen in a leap year. Each Ekādaśī day is purported to have particular benefits and blessings that are attained by the performance of specific activities.
Bhagavata Purana (sk. IX, adhy. 4) notes the observation of Ekādaśī by Ambarisha, a devotee of Lord Vishnu.Hindu calendar
Hindu calendar is a collective term for the various lunisolar calendars traditionally used in the Indian subcontinent. They adopt a similar underlying concept for timekeeping, but differ in their relative emphasis to moon cycle or the sun cycle and the names of months and when they consider the New Year to start. Of the various regional calendars, the most studied and known Hindu calendars are the Shalivahana Shaka found in South India, Vikram Samvat (Bikrami) found in North and Central regions of India, Tamil calendar used in Tamil Nadu, and the Bengali calendar used in the Bengal – all of which emphasize the lunar cycle. Their new year starts in spring. In contrast, in regions such as Kerala, the solar cycle is emphasized and this is called the Malayalam calendar, their new year starts in autumn, and these have origins in the second half of the 1st millennium CE. A Hindu calendar is sometimes referred to as Panchanga (पञ्चाङ्ग).The ancient Hindu calendar conceptual design is also found in the Jewish calendar, but different from the Gregorian calendar. Unlike Gregorian calendar which adds additional days to lunar month to adjust for the mismatch between twelve lunar cycles (354 lunar days) and nearly 365 solar days, the Hindu calendar maintains the integrity of the lunar month, but insert an extra full month by complex rules, every few years, to ensure that the festivals and crop-related rituals fall in the appropriate season.The Hindu calendars have been in use in the Indian subcontinent since ancient times, and remains in use by the Hindus in India and Nepal particularly to set the Hindu festival dates such as Holi, Maha Shivaratri, Vaisakhi, Raksha Bandhan, Pongal, Onam, Krishna Janmashtami, Durga Puja, Ram Navami, Pana Sankranti, Vishu and Diwali. Early Buddhist communities of India adopted the ancient Indian calendar, later Vikrami calendar and then local Buddhist calendars. Buddhist festivals continue to be scheduled according to a lunar system. The Buddhist calendar and the traditional lunisolar calendars of Cambodia, Laos, Myanmar, Sri Lanka and Thailand are also based on an older version of the Hindu calendar. Similarly, the ancient Jain traditions have followed the same lunisolar system as the Hindu calendar for festivals, texts and inscriptions. However, the Buddhist and Jain timekeeping systems have attempted to use the Buddha and the Mahavira's lifetimes as their reference points.The Hindu calendar is also important to the practice of Hindu astrology and zodiac system.Lunar calendar
A lunar calendar is a calendar based upon the monthly cycles of the Moon's phases (synodic months), in contrast to solar calendars, whose annual cycles are based only directly upon the solar year. The most commonly used calendar, the Gregorian calendar, is a solar calendar system that originally evolved out of a lunar calendar system. A purely lunar calendar is also distinguished from a lunisolar calendar, whose lunar months are brought into alignment with the solar year through some process of intercalation. The details of when months begin varies from calendar to calendar, with some using new, full, or crescent moons and others employing detailed calculations.
Since each lunation is approximately 29 1⁄2 days (29 days, 12 hours, 44 minutes, 3 seconds, or 29.530588 days), it is common for the months of a lunar calendar to alternate between 29 and 30 days. Since the period of twelve such lunations, a lunar year, is only 354 days, 8 hours, 48 minutes, 34 seconds (354.367056 days), purely lunar calendars lose around 11 days per year relative to the Gregorian calendar. In purely lunar calendars like the Islamic calendar, the lack of intercalation causes the lunar months to cycle through all the seasons of the Gregorian year over the course of a 33 lunar-year cycle.
Although the Gregorian calendar is in common and legal use in most countries, traditional lunar and lunisolar calendars continue to be used throughout the Old World to determine religious festivals and national holidays. Examples of such holidays include Ramadan (Islamic calendar); Easter; the Chinese, Japanese, Korean, Vietnamese, and Mongolian New Year (Chinese, Japanese, Korean, Vietnamese, and Mongolian calendars); the Nepali New Year (Nepali calendar); the Mid-Autumn Festival and Chuseok (Chinese and Korean calendars); Loi Krathong (Thai calendar); Sunuwar calendar; Vesak/Buddha's Birthday (Buddhist calendar); Diwali (Hindu calendars); and Rosh Hashanah (Hebrew calendar).Magha Puja
Māgha Pūjā (also written as Macha Bucha Day) is the second most important Buddhist festival, celebrated on the full moon day of the third lunar month in Cambodia, Laos, Thailand, Sri Lanka and on the full moon day of Tabaung in Myanmar. It celebrates a gathering that was held between the Buddha and 1,250 of his first disciples, which, according to tradition, preceded the custom of periodic recitation of discipline by monks. On the day, Buddhists celebrate the creation of an ideal and exemplary community, which is why it is sometimes called Saṅgha Day, the Saṅgha referring to the Buddhist community, and for some Buddhist schools this is specifically the monastic community. In Thailand, the Pāli term Māgha-pūraṇamī is also used for the celebration, meaning 'to honor on the full moon of the third lunar month'. Finally, some authors have also referred to the day as the Buddhist All Saints Day.Celebration of Māgha Pūjā is first known of in the modern period, with the institution of it in Thailand, by King Rama IV (1804–68). It is a public holiday in many Southeast Asian countries and is an occasion when Buddhists go to the temple to perform merit-making activities, such as alms giving, meditation and listening to teachings. It has been proposed as a more spiritual alternative to the celebration of Valentine's Day.Mount Putuo
Mount Putuo (Chinese: 普陀山; pinyin: Pǔtúo Shān; literally: '(from Sanskrit) Mount Potalaka') is an island southeast of Shanghai, in Zhoushan prefecture of Zhejiang province, China. It is a renowned site in Chinese Buddhism, and is considered the bodhimanda of the bodhisattva Avalokitesvara (Guanyin). Mount Putuo is one of the four sacred mountains in Chinese Buddhism, the others being Mount Wutai, Mount Jiuhua, and Mount Emei (Bodhimandas for Manjusri, Ksitigarbha, and Samantabhadra respectively).
Mount Putuo lies in the East China Sea and incorporates the beauty of both mountain and sea. Mountain Putuo is at 29°58′3～30°02′3 north latitude, 122°21′6～122°24′9 east longitude. Its area is approximately 12.5 square kilometres (4.8 sq mi) and there are numerous famous temples. Every year on the 19th day of the 2nd lunar month, 19th day of the 6th lunar month, and 19th day of the 9th lunar month of the Chinese calendar, it welcomes millions of people for the celebration of the birth of Guanyin.Pa Then people
The Pa Then (or Pá Hưng; Vietnamese: người Pà Thẻn) are an ethnic group of Vietnam. Most Pa Then live in Hà Giang and Tuyên Quang provinces, located in Vietnam's Northeast region. The Pa-Hng language belongs to the Hmong–Mien language family.
In 1999, the Pa Then numbered approximately 5,500 people.Paksha
Paksha (or pakṣa: Sanskrit: पक्ष) refers to a fortnight or a lunar phase in a month of the Hindu lunar calendar.Literally meaning "side", a paksha is the period either side of the Full Moon Day (Purnima). A lunar month in the Hindu calendar has two fortnights, and begins with the New moon, (Amavasya). The lunar days are called tithis and each month has 30 tithis, which may vary from 20 – 27 hours. A paksha has 15 tithis, which are calculated by a 12 degree motion of the Moon. The first fortnight between New Moon Day and Full Moon Day is called “Gaura Paksha” or Shukla Paksha, the period of the brightening moon (waxing moon), and the second fortnight of the month is called “Krishna Paksha”, or Vadhya Paksha, the period of the fading moon (waning moon). Nimach Panchang begin new lunar month from first day of Krishna Paksha while Gujarat Panchang begin new lunar month from first day of Shukla Paksha.Public holidays in North Korea
This is a list of public holidays in North Korea. See also the Korean calendar for a list of traditional holidays. As of 2017, the North Korean calendar has 71 official public holidays, including Sundays. In the past, North Koreans relied on rations provided by the state on public holidays for feasts. Recently, with marketization people are able to save up money and buy the goods they need.The Day of the Sun, the birthday of its founder and first leader Kim Il-sung, on 15 April is the most important holiday in the country. The second most important is the Day of the Shining Star on 16 February, the birthday of Kim Jong-il. As of 2019, Kim Jong-un's birthday is still not a public holiday. Other holidays of great importance are the Party Foundation Day (10 October) and the Day of the Foundation of the Republic (9 September). North Koreans often schedule their wedding days on important national holidays.North Korea regularly carries out missile and nuclear tests on such important anniversaries.Public holidays in Thailand
Public holidays in Thailand are regulated by the government, and most are observed by both the public and private sectors. There are usually sixteen public holidays in a year, but more may be declared by the cabinet. Other observances, both official and non-official, local and international, are observed to varying degrees throughout the country.
All public holidays are observed by government agencies, while the Bank of Thailand regulates bank holidays, which differ slightly from those observed by the government. Private businesses are required by the Labour Protection Act to observe at least 13 holidays per year, including National Labour Day, but may choose the other observances they follow. If a holiday falls on a weekend, one following workday is observed by the government as a compensatory holiday.Saionji no Kishi
Saionji no Kishi (西園寺 禧子, 1303 – 19 November 1333) was an Empress consort of Japan. She was the consort of Emperor Go-Daigo of Japan.
She was the 3rd daughter of Saionji Sanekane (西園寺実兼). She married with then Crown Prince Takaharu (later Emperor Go-Daigo) in 1313. Prince Takaharu acceded to the throne as Emperor Go-Daigo in the 2nd lunar month, 1318 and Kishi was made a lady-in-waiting in the 4th lunar month the same year. She was made Empress consort in the 8th lunar month, 1319. Emperor Go-Daigo was captured and exiled to the Oki Islands by the Ashikaga shogunate in the 3rd lunar month, 1332 and Kishi became a Buddhist nun in the 8th month the same year. Emperor Go-Daigo escaped from the Oki Islands and returned to Kyoto in the 6th lunar month, 1333. After that, Kishi resumed the title of Empress consort and was made Empress Dowager soon afterwards. She died at the age of 31 on the 10th lunar month 12th, 1333.
princess (1314–?), died young
Imperial Princess Kanshi (懽子内親王) (Senseimon-in, 宣政門院) (1315–1362), Saiō at Ise Shrine; later, married to Emperor KōgonSha'ban
Sha'ban (Arabic: شَعْبَان, romanized: sha‘bān) is the eighth month of the Islamic calendar.
This is the month of "separation", so called because the pagan Arabs used to disperse in search of water.
The fifteenth night of this month is known as the "Night of Records" (Laylat al-Bara'at). However, observance of this day is disputed.Sha'ban is the last lunar month before Ramadan, and so Muslims determine in it when the first day of Ramadan fasting will be.Shashthi (day)
Shashthi (Sanskrit: Ṣaṣṭhī) also referred to as Chhath is the sixth day or tithi of a Paksha or fourteen-day phase of the moon. The word comes from the Sanskrit cardinal ṣaṣ (six), whence the ordinal number (linguistics) ṣaṣṭha (sixth), fem. ṣaṣṭhī (days of the paksha are feminine gender).
The sixth tithi, especially in the waxing period (shuklapaksha), is important in several rituals including:
Durga Puja (September–October, east India, Bengal)
Sitalsasthi (May–June, Orissa, neighbouring regions)
Skanda Shashti or Subramanya Shashti (November–December, south India, Tamil Nadu)
Chhath, a major sun-worshiping day of Hindus is celebrated on sixth day Shukla Paksha of Kartika.Skanda Shasti Vratham
The Skanda Shasti or Kanda Shasthi Vratham is an important observance. It is especially for Lord Muruga. The festival is observed in Aippasi. Devotees fast during these six days. Although the festival is dedicated to Lord Murugan, Shukla Paksha Sashti in the lunar month of Kartika is the more significant one of the two. Devotees fast for six days. This lasts on the Soorasamharam day. The day after Soorasamharam is Tiru Kalyanam. The day after Soorasamharam is known as Subramanya Shashti, or Kukke Subramanya Sashti. It falls during lunar month Margashirsha.Sho Dun Festival
The Sho Dun Festival (Tibetan: ༄༅། ཞོ་སྟོན།; Chinese: 雪頓節; pinyin: Xuĕdùn Jié), commonly known as the Yogurt Festival or Banquet is an annual festival held at Norbulingka or "Jewel Park" palace in Lhasa, Tibet Autonomous Region.
The festival is celebrated in the summer, from the 15th to the 24th of the 5th lunar month - usually about the middle of August, after a month's retreat by the monks who stay within their monasteries to avoid walking on the emerging summer insects and killing them.
It began in the 16th century with a banquet given by the lay people for the monks featuring yogurt. Later on, summer operas, or Lhamo, and theatricals were added to the festivities. The operas, "last all day with clashing cymbals, bells and drums; piercing recitatives punctuating more melodious choruses; hooded villains, leaping devils, swirling girls with long silk sleeves. In the past dancers came from all over Tibet, but today there is only the state-run Lhasa Singing and Dancing Troupe."The beautiful grounds of the Norbulingka are filled with partying groups shielded from the wind by gaily coloured hanging walls of rugs and printed canvas. There is much feasting and visiting between family groups and bonfires are common at night.Trần dynasty
The Trần dynasty (Nhà Trần, 陳朝, Trần triều) ruled in Vietnam (then known as Đại Việt) from 1225 to 1400. The dynasty was founded when emperor Trần Thái Tông ascended to the throne after his uncle Trần Thủ Độ orchestrated the overthrow of the Lý dynasty. The final emperor of the dynasty was Thiếu Đế, who at the age of five years was forced to abdicate the throne in favor of his maternal grandfather, Hồ Quý Ly. The Trần dynasty defeated three Mongol invasions, most notably in the decisive Battle of Bạch Đằng River in 1288.Uposatha
The Uposatha (Sanskrit: Upavasatha) is a Buddhist day of observance, in existence from the Buddha's time (600 BCE), and still being kept today in Buddhist countries. The Buddha taught that the Uposatha day is for "the cleansing of the defiled mind," resulting in inner calm and joy. On this day, both lay and ordained members of the sangha intensify their practice, deepen their knowledge and express communal commitment through millennia-old acts of lay-monastic reciprocity. On these days, the lay followers make a conscious effort to keep the Five Precepts or (as the tradition suggests) the eight precepts. It is a day for practicing the Buddha's teachings and meditation.
