Oan Lunar Calendar
The Oan Lunar Calendar (Oan: Maramataka or Te Porotitira Marama Oa, OLC) is the official calendar of the Oan Isles. It is based on the cycles of Olune. The Oan Lunar Calendar was developed at least 4000 years ago. As chronographic technology has been developed, the calendar has been developed. During the reign of Ahua the Great, the calendar was separated into Before the Unification of the Oan Isles (BU) to After the Unification of the Oan Isles (AU). Thus, the Oan Isles is currently in year 1021 AU (which is 2021 CE). The Oan calendar starts during the month of Pipiri and is called Whakanui o te Matariki (shortened to Matariki and is the only secular holiday of the Oan Isles) (which spans May-June of the International Standard Calendar (CE)).
