Militiregnum
The year in Militiregnum lasts 366 days, 16 hours, 9 minutes and 33 seconds (approximately 366.673297 days). As such all Militiregnum calendars for many years now consist of 367 days, except every three years (leap years) when the year has a day less. However, every 144 years, there is no leap year, unless it's the 2880th year.
The Valiros Calendar
Originally created in Britay by astronomers employed by Lord Valiros, Founder of Britay, this calendar has received alterations since, but still retains the same name. It is mainly used in Western Militiregnum (Siltia, Nordland and Elepharia), though after the arrival of thedude, use of the thedudian Calendar was enforced instead, in official terms at least. The Alnnar and Tivelian regions have also been known to make use of it occasionally, along with the Cheinese and other varying local ones.
The Valiros Calendar has 12 months and the first day of the year is February 31st though in celebrations of the New Year, it is often considered the last day of the previous year also. A list of the months' day counts and notable dates (not complete) follows:
March: 31 days
25th: Vernal Equinox*
31st: Day of the Skyfalls
April: 30 days
May: 31 days
June: 30 days
26th: Estival Solstice*
July: 31 days
August: 31 days
September: 30 days
27th: Autumnal Equinox*
October: 31 days

December: 31 days
25th: Yuletide
26th: Hibernal Solstice*
January: 30 days
February: 31 days
31st: End of Year and New Year
- Note that the dates for the solstices and equinoctes are based on the dates they most often fall on, but can vary from 24 to 28.
The Valiros Calendar counts years based on the Figoranol system, traditionally defining it so by attributing to the year of Britay's founding the number 451 AF.
thedudian Calendar
The thedudian Calendar is a variant of the Valiros one that was formed after thedude's conquest of Morcia and replaced the Valiros Calender officially. The most noteable changes in it are the change of New Year's to April 1st in commemoration of his conquest of Morcia being official on that day (with the Battle of the Skyfalls having taken place on March 31st); and the counting of years as Years of thedude, that is the year after his conquest of Morcia (from April 1st after the Battle of the Skyfalls to the next March 31st) being defined as 1 Yt.
