This template computes a Julian day for Songkran, using specified year (or system year, in case of blank argument). The number has to be converted back to corresponding date, using Template:JULIANDAY.DAY, Template:JULIANDAY.MONTH, Template:JULIANDAY.YEAR.

There are two key dates during Songkran: (1) Maha Songkran and (2) Thaloengsok. Maha Songkran is when the Sun enters Aries and marks the start of celebration, which ends as new year begins on Thaloengsok. The result matches most Songkran notice made by many astrologers and calendar made by Government Savings Bank of Thailand. This is still adhered by many people, including monks and astrologers today, rather than government's fixed date (13 - 15 April).
