Visakha Bucha Day

[SymS]

I understand that Visakha Bucha Day is the day of the full moon of the sixth lunar month.

The full moon will be on the 20th of May, but buddha day is on the 19th?

Why is that?

According to all the calendars in Thailand, the 19th is the full moon. This is something I have noticed before, that an American/Western calendar shows the full moon a day after the full moon in Asia. Nothing to do with Buddhism I am afraid, but perhaps something to do with the international date line??

I tried to google the answer but couldn't find anything, your answer makes a lot of sense though!

One thing I did find is that on leap year Visakha Puja is supposed to be in June. This year is leap year and it's obviously not the case, though I did read something that implied there was such a thing as a lunar leap year that was different from the calendar leap year. Does anyone know anything about this?
