Heraldry of Kislev
Three dating systems are in common use in Kislev, although many more exist.[1a]
The most popular is the Gospodarin Calendar, which is state-supported, and thus used in all official documents. Like the Imperial Calendar, it breaks the year into 12 months and each month into four eight-day weeks, but there are no intercalary festivals, and the year begins on a different date: Shoika Day, on the Summer Solstice. As there are no festivals between the months, there are exactly 50 weeks in a year. The calendar begins from the date Khan-Queen Shoika founded the city of Kislev, which happened halfway though 1524 IC.[1a]
The second most popular dating system in Kislev is the Imperial Calendar, which is commonly referred to in Kislevite cities and is sometimes used by communities along the Imperial border. Its growing popularity betrays just how influential the Empire has become in Kislev. Indeed, many official documents and the few printed periodicals of the kingdom use both the Imperial and Gospodarin Calendar side-by-side.[1a]
Finally, there is the Ungol Calendar. This is mostly used by northern tirsas and stanistas of Ungol descent, and is most commonly used in settlements north of the River Lynsk. It uses a four-year cycle called an Urtza, and begins on the year the Ungols believe the Bear God Ursun first awoke from hibernation (ca. 500 IC). However, it is poorly documented, and date disparities between communities and variations of terminology are common. Indeed, most communities have their own names for the 24 (or, sometimes, 26 or 36) monthly divisions of the Urtza, which makes communication of dates using the calendar difficult, if not impossible.[1a]
