The birth date of Chinghis Khaan as determined through Mongolian astrology

Tibetan sources indicate that Genghis Khan, the founder of the Mongol Empire, was born in 1182, but this date is contradicted by Mongolian chronicles and Arab writings. A famous Mongolian historian and scientist subsequently fixed the birth date on the 31^st of May, 1162. Starting from the Mongolian astrological birth date of Genghis Khan, it is possible to recalculate the exact day and situate it on the 1^st of May, 1162.
