Buddha’s Birthday — April 8, i.e., Today, Is NOT Universally Celebrated/Accepted As Such.
Hence the widely celebrated holiday of Vesak — which is on the month of May Full Moon.
So celebrating the Buddha’s birthday on April 8th seems strange.
Yes, of course, one could have worked backwards and tried to determine when the Full Moon was in ‘that month’. It would not have been April or May. Those are European creations that make centuries later. So, trying to nail a specific date would be hard and quite ‘hit or miss’.
Big difference between April and May — and a fixed date vs. the Full Moon.
Just wanted to make sure YOU appreciated that April 8th is not universally accepted or celebrated as the Buddha’s birthday. Not by a long chalk.
