When Is Buddha's Birthday?

Varying Dates and Many Forms of Celebration

On what day is Buddha's birthday? That's simple. Just calculate the first full moon day of the sixth month of the Buddhist lunar calendar, which would be the fourth month of the Chinese calendar, except in years in which there's an extra full moon, and then Buddha's birthday falls in the seventh month. Well, except where it starts a week earlier. And in Tibet it's usually a month later. Oh, and in Japan, Buddha's birthday always is April 8.

Or, you could follow the guide below. For more about how Buddha's birthday is celebrated, see "Buddha's Birthday." For dates for the current year, see the Buddhist Holiday Calendar.

Saga Dawa is the entire fourth month of the Tibetan calendar, which usually begins in May and ends in June. The seventh day of Saga Dawa is the date of the historical Buddha's birth for Tibetans.

However, the Buddha's birth, enlightenment, and entry into Nirvana at his death are observed together on the 15th day of Saga Dawa, called Saga Dawa Duchen. This is the single most important holiday for Tibetan Buddhism, usually observed with pilgrimages and other visits to temples and shrines.
