In Western Zerith, the most commonly used calendar was implemented by Erste Nerin IV, an Emperor of the Second Imperium. It was said to have been created by a council of Court advisers. The calendar is divided into four seasons of three 30-day months each, separated by a day-long holiday that is not part of any month. There is another holiday day to start the year (which immediately follows Year’s End Day).
Holiday: New Year’s Day
Holiday: Winter’s Eve
Holiday: Sun Day
Holiday: Year’s End Day
Years are counted from the founding of the First Zerithian Empire, and are denoted with the initials IY, for Imperial Year.
