Common Era calendar: Difference between revisions

The '''Common Era calendar,''' also known as the '''Gregorian calendar''' or the '''Christiean calendar''', is the primary international standard calendar used among countries on [[Urth]]. While other countries, such as [[Asendavia]], [[Alksearia]], [[The Oan Isles]] and others use their own calendars internally (eg., [[Oan Lunar Calendar]]), nearly every country uses the Common Era calendar at least for the purposes of international commerce and diplomatic negotiations. The calendar was first devised and introduced by the International Common Calendar Conference that took place at Rilanon, [[Christie Island]], in June and July of the year 1701. It has also been adopted by several countries who did not send delegates to the conference. The document produced by the conference is known as the Christie Decree.

The calendar is a solar calendar in which a year is an average of 365.2425 days in length. An extra day of the year, called a "leap day," is added to the calendar according to rule in order to keep the calendar in alignment with the seasons. Years with this additional day are known as "leap years."
