Coscivian calendar

One of the most striking features of the Coscivian calendar system is its intricacy. It offers a multi-dimensional method of structuring time, combining information about lunar days, solar days, lunar months, solar months, the movements of the Sun and the Moon in relation to stellar constellations, and other astronomically defined time spans. This makes the Coscivian calendar vastly more complex than the Occidental calendars, which are built primarily around two basic units of time: solar days and solar years. To complicate things even further, there is not one single Coscivian calendar. Different sub-cultures and regions use their own variant of the classical system. The Federalist Calendar or Rektaséga Calendar, the official standardized calendar of the Kiravian Federacy since 17XY, represents but one of many variations of the Coscivian calendar. Still, there are some features that are common to all or most variants. These are presented below.
