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".
Common Era (CE) and Before the Common Era (BCE) are year notations for the Gregorian calendar, the world's most widely used calendar era. Common Era and Before the Common Era are alternatives to the Anno Domini notations used by Dionysius Exiguus. The two notation systems are numerically equivalent: "2022 CE" and "AD 2022" each describe the current year; "400 BCE" and "400 BC" are the same year.
Easter is a Christian festival and cultural holiday commemorating the resurrection of Jesus from the dead, described in the New Testament as having occurred on the third day of his burial following his crucifixion by the Romans at Calvary c. 30 AD. It is the culmination of the Passion of Jesus, preceded by Lent, a 40-day period of fasting, prayer, and penance.
ISO 8601 is an international standard covering the worldwide exchange and communication of date- and time-related data. It is maintained by the Geneva-based International Organization for Standardization (ISO) and was first published in 1988, with updates in 1991, 2000, 2004, and 2019. The standard aims to provide a well-defined, unambiguous method of representing calendar dates and times in worldwide communications, especially to avoid misinterpreting numeric dates and times when such data is transferred between countries with different conventions for writing numeric dates and times.
The Julian calendar, proposed by Julius Caesar in AUC 708, was a reform of the Roman calendar. It took effect on 1 January AUC 709 , by edict. It was designed with the aid of Greek mathematicians and astronomers such as Sosigenes of Alexandria.
A time zone is an area that observes a uniform standard time for legal, commercial and social purposes. Time zones tend to follow the boundaries between countries and their subdivisions instead of strictly following longitude, because it is convenient for areas in frequent communication to keep the same time.
The Julian day is the continuous count of days since the beginning of the Julian period, and is used primarily by astronomers, and in software for easily calculating elapsed days between two events.
The age of Earth is estimated to be 4.54 ± 0.05 billion years (4.54 × 109 years ± 1%). This age may represent the age of Earth's accretion, or core formation, or of the material from which Earth formed. This dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples.
Leif Erikson, Leiv Eiriksson or Leif Ericson, also known as Leif the Lucky, was a Norse explorer who is thought to have been the first European to have set foot on continental North America, approximately half a millennium before Christopher Columbus. According to the sagas of Icelanders, he established a Norse settlement at Vinland, which is usually interpreted as being coastal North America. There is ongoing speculation that the settlement made by Leif and his crew corresponds to the remains of a Norse settlement found in Newfoundland, Canada, called L'Anse aux Meadows and which was occupied 1,000 years ago.
Date Masamune was a regional ruler of Japan's Azuchi–Momoyama period through early Edo period. Heir to a long line of powerful daimyō in the Tōhoku region, he went on to found the modern-day city of Sendai. An outstanding tactician, he was made all the more iconic for his missing eye, as Masamune was often called dokuganryū (独眼竜), or the "One-Eyed Dragon of Ōshu".
The International Date Line (IDL) is an internationally accepted demarcation on the surface of Earth, running between the South Pole and North Pole and serving as the boundary between one calendar day and the next. It passes through the Pacific Ocean, roughly following the 180° line of longitude and deviating to pass around some territories and island groups. Crossing the date line eastbound decreases the date by one day or 24 hours, while crossing the date line westbound increases the date by one day or 24 hours.
Courtship is the period wherein a couple get to know each other prior to a possible marriage. Preceded by a proposal, courtship traditionally begins after a betrothal and concludes with the celebration of marriage. A courtship may be an informal and private matter between two people or may be a public affair, or a formal arrangement with family approval. Traditionally, in the case of a formal engagement, it is the role of a male to actively "court" or "woo" a female, thus encouraging her to understand him and her receptiveness to a marriage proposal.
Old Style (O.S.) and New Style (N.S.) indicate dating systems before and after a calendar change, respectively. Usually, this is the change from the Julian calendar to the Gregorian calendar as enacted in various European countries between 1582 and the 20th century.
The Batman is an American animated television series based on the DC Comics superhero Batman. Developed by Michael Goguen and Duane Capizzi, and produced by Warner Bros. Animation and Warner Bros. Television Studios, the series first aired on Kids' WB on September 11, 2004, then Cartoon Network on April 2, 2005. The show would become exclusive to the former network for its third, fourth, and fifth seasons in early 2006. The Batman won six Daytime Emmy Awards over the course of its run. Many elements from previous Batman storylines were borrowed and adapted, such as those from the comic books, film series and the animated shows like Batman: The Animated Series from the DC Animated Universe, but it remained strictly within its own distinct continuity. Jackie Chan Adventures artist Jeff Matsuda served as art director and provided the character designs. The production team altered the appearances of many of the comic books' supervillains for the show, such as the Joker, the Penguin, and the Riddler.
This is a list of tables of the oldest people in the world in ordinal ranks. To avoid including false or unconfirmed claims of old age, names here are restricted to those people whose ages have been validated by an international body dealing in longevity research, such as the Gerontology Research Group (GRG) or Guinness World Records (GWR), and others who have otherwise been reliably sourced.
Eiludd Powys was an early 7th-century King of Powys.
The Gregorian calendar is the calendar used in most of the world. It was introduced in October 1582 by Pope Gregory XIII as a modification of, and replacement for, the Julian calendar. The principal change was to space leap years differently so as to make the average calendar year 365.2425 days long, more closely approximating the 365.2422-day 'tropical' or 'solar' year that is determined by the Earth's revolution around the Sun. The rule for leap years is:
Every year that is exactly divisible by four is a leap year, except for years that are exactly divisible by 100, but these centurial years are leap years if they are exactly divisible by 400. For example, the years 1700, 1800, and 1900 are not leap years, but the years 1600 and 2000 are.
The regnal years of English monarchs are the official regnal years of the monarchs of the Kingdom of England from 1066, the Kingdom of Great Britain from May 1707 to January 1801, and the United Kingdom since January 1801. The regnal calendar continues to be used in many official British government and legal documents of historical interest, notably parliamentary statutes.
