Year 1 BC was a common year starting on Friday or Saturday (link will display the full calendar) of the Julian calendar (the sources differ, see leap year error for further information) and a leap year starting on Thursday of the Proleptic Julian calendar. It is also a leap year starting on Saturday, in the Proleptic Gregorian calendar. At the time, it was known as the Year of the Consulship of Lentulus and Piso (or, less frequently, year 753 Ab urbe condita). The denomination 1 BC for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. The following year is 1 AD in the widely used Julian calendar, which does not have a "year zero".

This article concerns the period between 9 BC and 1 BC, the last nine years of the Before Christ era.
This is a list of events occurring in the '''0s BC''' ordered by year.1st millennium BC
The 1st millennium BC is the period of time between from the year 1000 BC to 1 BC (10th to 1st centuries BC; in astronomy: JD 1356182.5 – 1721425.5).
It encompasses the Iron Age in the Old World and sees the transition from the Ancient Near East to Classical Antiquity.
World population roughly doubled over the course of the millennium,
from about 100 million to about 200–250 million.AD 1
AD 1 (I), 1 AD or 1 CE is the epoch year for the Anno Domini calendar era. It was the first year of the Common Era (CE), of the 1st millennium and of the 1st century. It was a common year starting on Saturday or Sunday, a common year starting on Saturday by the proleptic Julian calendar, and a common year starting on Monday by the proleptic Gregorian calendar. In its time, year 1 was known as the Year of the Consulship of Caesar and Paullus, named after Roman consuls Gaius Caesar and Lucius Aemilius Paullus, and less frequently, as year 754 AUC (ab urbe condita) within the Roman Empire. The denomination "AD 1" for this year has been in consistent use since the mid-medieval period when the anno Domini (AD) calendar era became the prevalent method in Europe for naming years. It was the beginning of the Christian/Common era. The preceding year is 1 BC; there is no year 0 in this numbering scheme. The Anno Domini dating system was devised in AD 525 by Dionysius Exiguus.
The Julian calendar, a 45 BC reform of the Roman calendar, was the calendar used by Rome in AD 1.Alcalá de Henares
Alcalá de Henares (Spanish pronunciation: [alkaˈla ðe eˈnaɾes]) is a Spanish city located 35 kilometres (22 miles) northeast of the country's capital, Madrid. It stands out for its rich archaeology and was one of the first bishoprics founded in Spain. Locally, it is generally known simply as "Alcalá", but "de Henares" is appended when needed to differentiate it from a dozen Spanish cities sharing the name Alcalá (from the Arabic word al-qal'a القلعة for fortification or citadel, typically a castle). The Latin name, Complutum, is sometimes used. The city is the capital of its namesake region, Comarca de Alcalá. Its historical centre is one of UNESCO's World Heritage Sites. Since his investiture after the 2015 local election the Mayor is Javier Rodríguez Palacios (PSOE).Anno Domini
The terms anno Domini (AD) and before Christ (BC) are used to label or number years in the Julian and Gregorian calendars. The term anno Domini is Medieval Latin and means "in the year of the Lord", but is often presented using "our Lord" instead of "the Lord", taken from the full original phrase "anno Domini nostri Jesu Christi", which translates to "in the year of our Lord Jesus Christ".
This calendar era is based on the traditionally reckoned year of the conception or birth of Jesus of Nazareth, with AD counting years from the start of this epoch, and BC denoting years before the start of the era. There is no year zero in this scheme, so the year AD 1 immediately follows the year 1 BC. This dating system was devised in 525 by Dionysius Exiguus of Scythia Minor, but was not widely used until after 800.The Gregorian calendar is the most widely used calendar in the world today. For decades, it has been the unofficial global standard, adopted in the pragmatic interests of international communication, transportation, and commercial integration, and recognized by international institutions such as the United Nations.Traditionally, English followed Latin usage by placing the "AD" abbreviation before the year number. However, BC is placed after the year number (for example: AD 2019, but 68 BC), which also preserves syntactic order. The abbreviation is also widely used after the number of a century or millennium, as in "fourth century AD" or "second millennium AD" (although conservative usage formerly rejected such expressions). Because BC is the English abbreviation for Before Christ, it is sometimes incorrectly concluded that AD means After Death, i.e., after the death of Jesus. However, this would mean that the approximate 33 years commonly associated with the life of Jesus would neither be included in the BC nor the AD time scales.Terminology that is viewed by some as being more neutral and inclusive of non-Christian people is to call this the Current or Common Era (abbreviated as CE), with the preceding years referred to as Before the Common or Current Era (BCE). Astronomical year numbering and ISO 8601 avoid words or abbreviations related to Christianity, but use the same numbers for AD years.Antiochus VI Dionysus
Antiochus VI Dionysus (c. 148–142/1 BC), king of the Hellenistic Seleucid kingdom, was the son of Alexander Balas and Cleopatra Thea, daughter of Ptolemy VI of Egypt.Astronomical year numbering
Astronomical year numbering is based on AD/CE year numbering, but follows normal decimal integer numbering more strictly. Thus, it has a year 0; the years before that are designated with negative numbers and the years after that are designated with positive numbers. Astronomers use the Julian calendar for years before 1582, including the year 0, and the Gregorian calendar for years after 1582, as exemplified by Jacques Cassini (1740), Simon Newcomb (1898) and Fred Espenak (2007).The prefix AD and the suffixes CE, BC or BCE (Common Era, Before Christ or Before Common Era) are dropped. The year 1 BC/BCE is numbered 0, the year 2 BC is numbered −1, and in general the year n BC/BCE is numbered "−(n − 1)" (a negative number equal to 1 − n). The numbers of AD/CE years are not changed and are written with either no sign or a positive sign; thus in general n AD/CE is simply n or +n. For normal calculation a number zero is often needed, here most notably when calculating the number of years in a period that spans the epoch; the end years need only be subtracted from each other.
The system is so named due to its use in astronomy. Few other disciplines outside history deal with the time before year 1, some exceptions being dendrochronology, archaeology and geology, the latter two of which use 'years before the present'. Although the absolute numerical values of astronomical and historical years only differ by one before year 1, this difference is critical when calculating astronomical events like eclipses or planetary conjunctions to determine when historical events which mention them occurred.Century
A century (from the Latin centum, meaning one hundred; abbreviated c.) is a period of 100 years. Centuries are numbered ordinally in English and many other languages.
A centenary is a hundredth anniversary, or a celebration of this, typically the remembrance of an event which took place a hundred years earlier.Didacticism
Didacticism is a philosophy that emphasizes instructional and informative qualities in literature and other types of art.Emperor Ai of Han
Emperor Ai of Han (27 BC – 15 August 1 BC) was an emperor of the Chinese Han Dynasty. He ascended the throne when he was 20, having been made heir by his childless uncle Emperor Cheng, and he reigned from 7 to 1 BC.
The people and the officials were initially excited about his ascension, as he was viewed by them (as well as Emperor Cheng) to be intelligent, articulate, and capable. However, under Emperor Ai, corruption became even more prevalent and heavy taxes were levied on the people. Furthermore, Emperor Ai was highly controlled by his grandmother Consort Fu (consort of his grandfather and his predecessor's father Emperor Yuan), who demanded the title of Grand Empress Dowager—even though she had never been an empress previously and therefore did not properly hold that title, and this led to the unprecedented and unrepeated situation of four women possessing empress dowager titles at the same time—Empress Wang (Emperor Cheng's mother and Emperor Yuan's wife), Empress Zhao Feiyan (Emperor Cheng's wife), Consort Fu, and Consort Ding (Emperor Ai's mother).
Consort Fu's control of the political scene extended until her death in 2 BC, including an episode where her jealousy of Consort Feng Yuan—another consort of Emperor Yuan's (and therefore her romantic rival) and the grandmother of the future Emperor Ping—resulted in Consort Feng being falsely accused of witchcraft and subsequently being forced to commit suicide. During Emperor Ai's reign, he also stripped the Wang clan (Empress Wang's clan), which had been powerful during Emperor Cheng's reign, of much of their power, and substituted members of the Fu and Ding clans in their stead (which, ironically, caused the people, who were not enamored with the Wangs initially, to long for their return to power as they associated the departure of the Wangs from power with Emperor Ai's incompetence in administration). In an unpopular act, Emperor Ai had his prime minister Wang Jia (王嘉, unrelated to the Wang clan mentioned above) put to death for criticizing him, an act that made him appear tyrannical. Emperor Ai's shortcomings quickly led to the demoralization of the people towards the government and the acquisition of power by Wang Mang, in a backlash, after Ai died in 1 BC.
Emperor Ai was also famous for being the most effusive homosexual emperor of the Han Dynasty. Traditional historians characterized the relationship between Emperor Ai and Dong Xian as one between homosexual lovers and referred to their relationship as "the passion of the cut sleeve" (斷袖之癖) after a story that one afternoon after falling asleep for a nap on the same bed, Emperor Ai cut off his sleeve rather than disturb the sleeping Dong Xian when he had to get out of bed. Dong was noted for his relative simplicity contrasted with the highly ornamented court, and was given progressively higher and higher posts as part of the relationship, eventually becoming the supreme commander of the armed forces by the time of Emperor Ai's death. Dong was afterward forced to commit suicide.List of years in Canada

A millennium (plural millennia or millenniums) is a period equal to 1000 years, sometimes called a kiloyear. It derives from the Latin mille, thousand, and annus, year. It is often, but not always, related to a particular dating system.
Sometimes, it is used specifically for periods of a thousand years that begin at the starting point (initial reference point) of the calendar in consideration (typically the year "1"), or in later years that are whole number multiples of a thousand years after it. The term can also refer to an interval of time beginning on any date. Frequently in the latter case (and sometimes also in the former) it may have religious or theological implications (see millenarianism).Olympiad
An Olympiad (Greek: Ὀλυμπιάς, Olympiás) is a period of four years associated with the Olympic Games of the Ancient Greeks. Although the Ancient Olympic Games were established during Archaic Greece, it was not until the Hellenistic period, beginning with Ephorus, that the Olympiad was used as a calendar epoch. Converting to the modern BC/AD dating system the first Olympiad began in the summer of 776 BC and lasted until the summer of 772 BC, when the second Olympiad would begin with the commencement of the next games.
By extrapolation to the Gregorian calendar, the
3rd year of the 699th Olympiad will begin in (Northern-Hemisphere) mid-summer 2019.
A modern Olympiad refers to a four-year period beginning on the opening of the Olympic Games for the summer sports. The first modern Olympiad began in 1896, the second in 1900, and so on (the 31st began in 2016: see the Olympic Charter).
The ancient and modern Olympiads would have synchronised had there been a year zero between the Olympiad of 4 BC and the one of 4 AD. But as the Gregorian calendar goes directly from 1 BC to 1 AD, the ancient Olympic cycle now lags the modern cycle by one year.Proleptic Gregorian calendar
The proleptic Gregorian calendar is produced by extending the Gregorian calendar backward to dates preceding its official introduction in 1582. In countries that adopted the Gregorian calendar later, dates occurring in the interim (between 1582 and the local adoption) are sometimes "Gregorianized" as well. For example, George Washington was born on February 11, 1731 (Old Style), as Great Britain and its possessions were using the Julian calendar with English years starting on March 25 until September 1752. After the switch, that day became February 22, 1732, which is the date commonly given as Washington's birthday.Proleptic Julian calendar
The proleptic Julian calendar is produced by extending the Julian calendar backwards to dates preceding AD 8 when the quadrennial leap year stabilized. The leap years that were actually observed between the implementation of the Julian calendar in 45 BC and AD 8 were erratic: see the Julian calendar article for details.
A calendar obtained by extension earlier in time than its invention or implementation is called the "proleptic" version of the calendar. Likewise, the proleptic Gregorian calendar is occasionally used to specify dates before the introduction of the Gregorian calendar in 1582. Because the Julian calendar was used before that time, one must explicitly state that a given quoted date is based on the proleptic Gregorian calendar if that is the case.
Note that the Julian calendar itself was introduced by Julius Caesar, and as such is older than the introduction of the Anno Domini era (or the "Common Era", counting years since the birth of Christ as calculated by Dionysus Exiguus in the 6th century, and widely used in medieval European annals since about the 8th century, notably by Bede). The proleptic Julian calendar uses Anno Domini throughout, including for dates of Late Antiquity when the Julian calendar was in use but Anno Domini wasn't, and for times predating the introduction of the Julian calendar.
Years are given cardinal numbers, using inclusive counting (AD 1 is the first year of the Anno Domini era, immediately preceded by 1 BC, the first year preceding the Anno Domini era, there is no "zeroth" year).
Thus, the year 1 BC of the proleptic Julian calendar is a leap year.
This is to be distinguished from the "astronomical year numbering", introduced in 1740 by French astronomer Jacques Cassini, which considers each New Year an integer on a time axis, with year 0 corresponding to 1 BC, and "year −1" corresponding to 2 BC, so that in this system, Julian leap years have a number divisible by four.
The determination of leap years in the proleptic Julian calendar (in either numbering) is distinct from the question of which years were historically considered leap years during the Roman era, due to the leap year error: Between 45 BC and AD 8, the leap day was somewhat unsystematic. Thus there is no simple way to find an equivalent in the proleptic Julian calendar of a date quoted using either the Roman pre-Julian calendar or the Julian calendar before AD 8. The year 46 BC itself is a special case, because of the historical introduction of the Julian calendar in that year, it was allotted 445 days. Before then, the Roman Republican calendar used a system of intercalary months rather than leap days.Psammuthes
Psammuthes was a pharaoh of the Twenty-ninth Dynasty of Egypt during 392/1 BC.Xin dynasty
The Xin dynasty (; Chinese: 新朝; pinyin: Xīncháo; Wade–Giles: Hsin¹-chʻao²; literally: 'New dynasty') was a Chinese dynasty (termed so despite having only one emperor) which lasted from 9 to 23 AD. It is often considered an interregnum period of the Han dynasty, dividing it into the Former or Western Han and the Latter or Eastern Han.
Wang Mang, the sole emperor of the Xin dynasty, was the nephew of Grand Empress Dowager Wang Zhengjun. After the death of her step-grandson Emperor Ai in 1 BC, Wang Mang rose to power. After several years of cultivating a personality cult, he finally proclaimed himself emperor in 9 AD. However, while a creative scholar and politician, he was an incompetent ruler, and it aroused the discontent of many people. After a while, the country became poor, and the peasants, merchants, and descendants of the former imperial clan rebelled. Despite the fact that Wang Mang had twice the number of soldiers and had a sturdy city wall surrounding his capital of Chang'an, the rebels used an ingenious invention to get over the city walls into the city and defeated his army. He died soon after the siege, and the Han dynasty was restored by descendants of the former imperial clan.Year zero
Year zero does not exist in the anno Domini system usually used to number years in the Gregorian calendar and in its predecessor, the Julian calendar. In this system, the year 1 BC is followed by AD 1. However, there is a year zero in astronomical year numbering (where it coincides with the Julian year 1 BC) and in ISO 8601:2004 (where it coincides with the Gregorian year 1 BC) as well as in all Buddhist and Hindu calendars.
