(If you’re reading this in Japan and I’m sure I have many readers there) it may be the birthday of Siddhartha Gautama. ACME would like to wish you Namo Amituofo –
Otherwise, 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.

And in Tibet it’s usually a month later.
This will be on the test
