How Thai year is calculated

Thai year showing on coins is counted from the death of the Buddha in 545 BC. For this reason, you'll often find in front of the year "พ.ศ." which is the abbreviation for "Buddhist era".

As an example, the coin on the right reads "พ.ศ. ๒๕๔๗" which means "2547 of the Buddhist era", that is 2004.

More on Thai dates

Since 1912, Thailand counts years from the parinirvana i.e. the death of the Buddha. Buddhist year 0 is Gregorian 545 BC.
Until 2483 (1940), the Thai year would begin on March 1st. However, year 2483 was shortened by 3 months so that Thai years begin on January 1st from 2484.

In order to convert a Thai year to Gregorian calendar, you need to substract 543.
Notice: From 1912 to 1940, Thai year spread across two Gregorian years. By substracting 543, you get the Gregorian year of the first 9 months of the Thai year.
