Public holidays in Thailand 2022-2026
Parts of the Thai calendar are based on the Gregorian calendar, which we also know in Germany. Nevertheless, there are isolated holidays which are calculated according to the original Thai lunisolar calendar. In addition, some holidays are determined individually each year not only according to astronomical, but even astrological aspects.Christian festivals such as Christmas are well known in Thailand and are also celebrated in large cities - but not for Christian reasons, but exclusively for social reasons.

The Thai Lunisolar Calendar

Month | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 |
---|---|---|---|---|---|---|---|---|---|---|---|---|
Days 1st year | 29 | 30 | 29 | 30 | 29 | 30 | 30 | 29 | 30 | 29 | 30 | 29 |
Days 2nd year | 30 | 29 | 30 | 29 | 30 | 29 | 29 | 30 | 29 | 30 | 29 | 30 |
In order to additionally consider the course of the sun, complex calculations are used to insert a leap day or even a whole leap month every few years. The 8th month of a year is simply doubled. A year has thus not always 12 months, but is also times 354, 355 or 384 days long. This alone makes it difficult to convert the beginning of the year into our Greogian calendar.
The holidays calculated according to this lunar calendar are Makha Bucha, Visakha Bucha, Asalha Puja, Khao Phansa, Sat Thai, Ok Phansa, the Kathin ceremony and Loi Krathong. Most of these ceremonies are held on full moon, only Sat Thai is celebrated on the day of the new moon. Since 1888 this calendar system is only used to calculate holidays. Except for the year, the Thai calendar since then corresponds to the Gregorian calendar.
