Celebrated on the full moon (the fifteenth day) of the first Tibetan lunar month, Chotrul Duchen (the ‘Day of Miracles’) is the first of four major prayer festivals in the Tibetan Buddhist calendar commemorating great events in the Buddha's life.  The “Day of Miracles” is celebrated by Tibetans from the first to the fifteenth of the first lunar month, so it is the first “Düchen” or “great occasion” in the Tibetan calendar, marking the beginning of the New Year. These fifteen days are “multiplying days” in which the effect of any action is magnified millions of times and the fifteenth day is especially great. Chotrul Düchen is a “ten million multiplier” day, multiplying the effects of all positive and negative actions 10 million times! It is therefore considered very beneficial to engage in positive activities on this day!
