Why are the dates only tentative?

The Loy Krathong date is tentative as the festival takes place on the night of the full moon of the 12th month of the Thai lunar calendar, which usually falls in November but on a different day. The official date of Loy Krathong is announced the year before.

The Yi Peng latern festival date is determined by the Lanna Lunar Calendar and typically starts one or two days before Loy Krathong.
