The Mongolian Lunar New Year, commonly known as Tsagaan Sar (Цагаан сар, Cagán sar / , t͡shaɢaːŋ sar or literally White Moon), is the first day of the year according to the Mongolian lunisolar calendar. The festival of the Lunar New Year is celebrated by the Mongols and some Turkic peoples. The holiday has shamanistic influences.
The White Moon festival is celebrated on the first through third days of the first lunar month. Tibet's Losar occurs on the same day as the Mongolian White Moon.
Tsagaan Sar is one of the most important Mongolian holidays. Originally, it was celebrated in spring.
The Mongols of Genghis Khan used the twelve-year animal cycle to mark their chronology. The Secret History of the Mongols written in 1240 as well as many letters of the Khans extensively use the twelve-year animal cycle. On the Year of the Red Hare, Genghis Khan ascended and purified himself on the first day of the lunar new year, wore new clothes, paid respects to Heaven and Earth, bowed and greeted his mother Hoelun and took part in a ceremony in his palace. On the first day of the lunar new year of the Year of the Rat (1216), Genghis Khan distributed gold presents to people aged over 60.
Marco Polo describes a Mongolian Lunar New Year (White Moon) celebrated by Kublai Khan in the 13th century during the Yuan Dynasty (1271-1368). In Book Two, Part One he writes:
The beginning of their New Year is the month of February, and on that occasion the Great Khan and all his subjects made such a Feast as I now shall describe. It is the custom that on this occasion the Khan and all his subjects should be clothed entirely in white; so, that day, everybody is in white, men and women, great and small. And this is done in order that they may thrive all through the year, for they deem that white clothing is lucky. On that day also all the people of all the provinces and governments and kingdoms and countries that owe allegiance to the Khan bring him great presents of gold and silver, and pearls and gems, and rich textures of divers kinds.
