Sart Thai day will be celebrated at Wat Tampa on Sunday, September 27, 2015 this year. Sart Thai day falls in the middle of the traditional Thai year. It occurs on the fifteenth day of the waning moon of the tenth lunar month (sometime during September).
The word Sart, derived from the Pali language, means season and in particular autumn or fall. Sart Thai day is also referred to as Memorial Day. This is not Memorial Day as Americans might assume. In Thailand, Sart Thai is a time to remember dead relatives with prayers, Buddhist rituals, and merit making on their behalf.
