Dates before 1941

In the historical Thai civil calendar, the year began in April before the 1941 reform. For January through March before 1941, add 542 to the A.D. year. For April through December, add 543. B.E. 2483 ran from April to December 1940. January 1, 1941 began B.E. 2484.

The historical option covers records dated 1 April 1913 onward. Choose modern conversion for a year already written using today’s convention. See the Thai Fine Arts Department’s calendar history.
