Question

what is first day of the Buddhisti calender​

Answer 1

Epochal date:

• As we know that in all Theravada traditions, the calendar's epochal year 0 date was the day in which the Buddha attained parinibbāna.
• However, not all traditions agree on when it actually took place. In the Burmese Buddhist tradition, it was 13 May 544 BCE (Tuesday, Full moon of Kason 148 Anjanasakaraj).

• The reckoning of the Buddhist Era in Thailand is 543 years ahead of the Common Era (Anno Domini), so the year 2021 CE corresponds to B.E. 2564.
• So, The lunar calendar contains 12 or 13 months in a year, with 15 waxing moons and 14 or 15 waning moon days in a month, amounting to years of 354, 355, or 384 days.
