Question

why the buddha purnima is not a day of rejoicing? give atleast 3 reasons

Answer 1

Vesak (Buddha Purnima, Buddha Jayanti) is a Buddhist festival that marks Gautama Buddha's birth, enlightenment and death. It falls on the day of the Full Moon in April or May and it is a gazetted holiday in India.
Buddha Purnima is called so in India because this auspicious day falls on the full moon day. On the full moon day of Vaishakha, the lunar month corresponds to the month of April-May. ... It is believed that Buddha achieved enlightenment and nirvana (salvation) on the same day.
