Thai National Holidays
A list of the national work holidays is given below. However, the exact day of the year of some of these will vary, as noted. The ones affected are those based on the lunar calendar, rather than the 365-day solar calendar. Lunar calendar events usually come on a full moon.
Before Thailand (and many western civilizations) switched to the solar 365-day calendar, a lunar calendar was used, whereby one month, or moonth, was 29 or 30 days, e.g., full moon to full moon (29.5 days). Since a solar year is not exactly 12 moonths, there is a shift from year to year between the lunar and solar calendar dates. Notably, the Thai lunar holidays that are in common with Chinese holidays and the holidays of other past lunar calendar cultures may not coincide with each other on the same date, because there are variations in the different implementations of the ancient lunar calendars.
