Tungsa Devi is the legendary daughter associated with Songkran when the first day falls on Sunday.
In the traditional Songkran legend, Thao Kabinlaphrom has seven daughters known as the Nang Songkran. Each daughter is linked to a day of the week and is traditionally depicted with particular clothing, a vehicle, and identifying objects.
Tungsa Devi is the Sunday daughter. The story is connected with the transition into the traditional New Year and helps explain why Nang Songkran figures appear in festival art, pageants, and processions.
The seven daughters are sometimes confused with historical queens or Buddhist deities. They are legendary figures in Thai New Year tradition, not documented historical rulers. Their attributes vary according to the weekday represented.
