Mongolian calendar
The Mongolian calendar may refer to a number of different lunisolar calendars related to the Chinese and Tibetan calendars. These calendars (Mongolian: цаглабар, romanized: tsaglabar or цаг тооны бичиг, tsag toony bichig) have largely been replaced in day-to-day use with the Gregorian calendar (Аргын тоолол, Argyn toolol, 'chronology of method'), however the traditional calendar (Билгийн тоолол, Bilgiin toolol, 'chronology of wisdom') is still used for a variety of traditions such as the date of festivals like Tsagaan Sar (the Mongolian new year), horoscopy, and zodiac signs.
