Circa (from Latin , meaning 'around, about, roughly, approximately') –frequently abbreviated ca. or c. and less frequently circ., cca. or cc. –signifies "approximately" in several European languages and as a loanword in English, usually in reference to a date. Circa is widely used in historical writing when the dates of events are not accurately known.
When used in date ranges, circa is applied before each approximate date, while dates without circa immediately preceding them are generally assumed to be known with certainty.
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".
A calendar is a system of organizing days for social, religious, commercial or administrative purposes. This is done by giving names to periods of time, typically days, weeks, months and years. A date is the designation of a single, specific day within such a system. A calendar is also a physical record of such a system. A calendar can also mean a list of planned events, such as a court calendar or a partly or fully chronological list of documents, such as a calendar of wills.
The French Republican calendar, also commonly called the French Revolutionary calendar, was a calendar created and implemented during the French Revolution, and used by the French government for about 12 years from late 1793 to 1805, and for 18 days by the Paris Commune in 1871. The revolutionary system was designed in part to remove all religious and royalist influences from the calendar, and was part of a larger attempt at decimalisation in France. It was used in government records in France and other areas under French rule, including Belgium, Luxembourg, and parts of the Netherlands, Germany, Switzerland, Malta, and Italy.
The Islamic calendar, also known as the Hijri, Lunar Hijri, Muslim or Arabic calendar, is a lunar calendar consisting of 12 lunar months in a year of 354 or 355 days. It is used to determine the proper days of Islamic holidays and rituals, such as the annual period of fasting and the proper time for the pilgrimage to Mecca. The civil calendar of almost all countries where the religion is predominantly Muslim is the Gregorian calendar, with Syriac month-names used in the Levant and Mesopotamia. Notable exceptions to this rule are Iran and Afghanistan, which use the Solar Hijri calendar. Rents, wages and similar regular commitments are generally paid by the civil calendar.
ISO 8601Data elements and interchange formats – Information interchange – Representation of dates and times is an international standard covering the exchange of date- and time-related data. It was issued by the International Organization for Standardization (ISO) and was first published in 1988. The purpose of this standard is to provide an unambiguous and well-defined method of representing dates and times, so as to avoid misinterpretation of numeric representations of dates and times, particularly when data is transferred between countries with different conventions for writing numeric dates and times.
The Julian calendar, proposed by Julius Caesar in 708 Ab urbe condita (46 BC), was a reform of the Roman calendar. It took effect on 1 January 709 AUC (45 BC), by edict. It was designed with the aid of Greek mathematicians and Greek astronomers such as Sosigenes of Alexandria.
Year 150 (CL) was a common year starting on Wednesday of the Julian calendar. At the time, it was known as the Year of the Consulship of Squilla and Vetus. The denomination 150 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.
Year 500 (D) was a leap year starting on Saturday of the Julian calendar. At the time, it was known as the Year of the Consulship of Patricius and Hypatius. The denomination 500 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 year 500 is considered the beginning of the Middle Ages, approximately.
Chronology is the science of arranging events in their order of occurrence in time. Consider, for example, the use of a timeline or sequence of events. It is also "the determination of the actual temporal sequence of past events".
Year 120 BC was a year of the pre-Julian Roman calendar. At the time it was known as the Year of the Consulship of Manilius and Carbo and the Third Year of Yuanshou. The denomination 120 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 Thai solar calendar was adopted by King Chulalongkorn in 1888 CE as the Siamese version of the Gregorian calendar, replacing the Thai lunar calendar as the legal calendar in Thailand. Years are now counted in the Buddhist Era (B.E.): พุทธศักราช, พ.ศ., which is 543 years ahead of the Gregorian calendar.
Jeconiah, also known as Coniah and as Jehoiachin, was the nineteenth and penultimate king of Judah who was dethroned by the King of Babylon, Nebuchadnezzar II in the 6th century BCE and was taken into captivity. He was the son and successor of King Jehoiakim. Most of what is known about Jeconiah is found in the Hebrew Bible. Records of Jeconiah's existence have been found in Iraq, such as the Jehoiachin's Rations Tablets. These tablets were excavated near the Ishtar Gate in Babylon and have been dated to c. 592 BCE. Written in cuneiform, they mention Jeconiah and his five sons as recipients of food rations in Babylon.
A calendar era is the period of time elapsed since one epoch of a calendar and, if it exists, before the next one. For example, the Gregorian calendar numbers its years in the Western Christian era.
Old Style (O.S.) and New Style (N.S.) are terms sometimes used with dates to indicate that the calendar convention used at the time described is different from that in use at the time the document was being written. There were two calendar changes in Great Britain and its colonies, which may sometimes complicate matters: the first was to change the start of the year from Lady Day to 1 January; the second was to discard the Julian calendar in favour of the Gregorian calendar. Closely related is the custom of dual dating, where writers gave two consecutive years to reflect differences in the starting date of the year, or to include both the Julian and Gregorian dates.
The Kings of Judah were the monarchs who ruled over the ancient Kingdom of Judah. According to the biblical account, this kingdom was founded after the death of Saul, when the tribe of Judah elevated David to rule over it. After seven years, David became king of a reunited Kingdom of Israel. However, in about 930 BCE the united kingdom split, with ten of the twelve Tribes of Israel rejecting Solomon's son Rehoboam as their king. The tribes of Judah and Benjamin remained loyal to Rehoboam, and re-formed the Kingdom of Judah, while the other entity continued to be called the Kingdom of Israel, or just Israel.
The Holocene calendar, also known as the Holocene Era or Human Era (HE), is a year numbering system that adds exactly 10,000 years to the currently dominant numbering scheme, placing its first year near the beginning of the Holocene geological epoch and the Neolithic Revolution, when humans transitioned from a hunter-gatherer lifestyle to agriculture and fixed settlements. The current year by the Gregorian calendar, AD 2020, is 12020 HE in the Holocene calendar. The HE scheme was first proposed by Cesare Emiliani in 1993.
The Calendar Act 1750 (c.23) was an Act of the Parliament of Great Britain. The Act had two parts: first, it reformed the calendar of England and the British Dominions so that the new legal year began on 1 January rather than 25 March ; and, second, Great Britain and its Dominions adopted the Gregorian calendar, as already used in most of western Europe.
The Gregorian calendar is the calendar used in most of the world. It is named after Pope Gregory XIII, who introduced it in October 1582.

The Fasti Ostienses are a calendar of Roman magistrates and significant events from 49 BC to AD 175, found at Ostia, the principal seaport of Rome. Together with similar inscriptions, such as the Fasti Capitolini and Fasti Triumphales at Rome, the Fasti Ostienses form part of a chronology known as the Fasti Consulares, or Consular Fasti.
