The Tibetan New Year, or Losar, is celebrated according to the lunar calendar. In 2016, Losar is February 9th. The night before Losar, the many offerings are beautifully arranged before the shrine. In the morning in monasteries and households alike, everyone will awake early, dress in new clothes and begin the day with special ritual offerings and prayers for a year of good fortune including raising prayer flags. Losar always begins with the New Moon and the offerings remain upon the shrine until after the night of the Full Moon.
This begins the year of the Fire Monkey. See previous post about the Monkey in Tibetan astrology: https://ravencypresswood.com/2015/10/11/the-twelve-animals-of-tibetan-astrology-the-snake/
