Imperial Calendar
The Imperial calendar is a fairly complex dating system resulting from centuries of modification by various Emperors and scholars. Only three days of each month are named, and all other days are listed by how far they are from one of these days. The Calends is the first day of any given month, the Nones is the fifth day and the Ides is the fifteenth day.
It is also important to note that when the Imperials count days they include both the start and end day of the time span in question. Thus, the 3rd of Folloch in Koramia would be the 4th day after the Calends of Tertilis to an Imperial. To contribute to the confusion in the Imperial dating system, there is no traditional convention as to which of the three days one counts from. Thus, the 4th day after the Calends of Tertilis is also the 2nd day before the Nones of Tertilis. It is also acceptable to merely list how many days into the month an event takes place, a convention used by those who must often write out dates such as bureaucrats and priests. Thus, the 3rd day after the Ides of Quinctilis can also be listed as the 18th of Quinctilis.
The Imperial calendar, called the Hieronymide Calendar, is based on the work of Hieronymous of House Sanctus and, thus, has different names for the months as well as a different New Year's Day. Whereas the new year begins on the 1st of Folloch (the first day of Spring) for the Koramians, the Hieronymide calendar begins on the 2nd day after the Nones of Ditilis (the 6th day of the month and the Winter solstice). Though the Davidian calendar has remained relatively unchanged since its creation, various Emperors have altered the Hieronymide calendar, typically by naming a month after themselves.
The calendar is dated from the election of the first Emperor of Zeth, Octavius of House Zetar, over 1350 years ago. The current year is 1354 IC.
