Aquian Calendar

The Aquian Calendar is the most popular system of timekeeping on Irdas. It is used not only in regions once controlled by the Aquian Empire, but across most of the world as well. It is the most accurate calendar in the world, and sets the standard for international trade and commerce. It is always accurate to within a day of the real annual orbit of Irdas around Casinia, which lasts 372.163 days. It also loosely follows the lunar cycles of Irdas's two moons, Lucia and Gastor, as well.

Rules
The Aquian calendar is defined by the following rules.
 * A year lasts 372 days.
 * A day is split into 24 hours, with 2 cyces of twelve hours split by the peak of the sun on the equinoxes.
 * Every 6th year, an additional day will be added to the beginning of the year to correct the calendar.
 * Every 300 years, the additional day will be ignored to further correct the calendar.
 * Every 3000 years, the last day of the year will be removed to even further correct the calendar.
 * The year is further arranged into 16 months, each of 23 or 24 days, which loosely follow the lunar cycles.
 * The year is also split into weeks, each of 6 days, loosely following the transition of a half phase of the moon Lucia.
