Thingyan is is celebrated at the same time as many other New Years in the region. Thingyan historically marked the changing of the year by the sun moving from Pieces to Aries. The word Thingyan is thought to have derived from ancient Sanskrit and means ‘change’.
This is an ancient festival and when it was first observed, the movement of the sun into Aries would have been closer to the Vernal Equinox (March 21st) which marks the arrival of spring in the northern hemisphere. The dates of these events differ today due to the wobble of the earth on its axis over a 25,000 cycle – known as procession.
The legend of the origin of Thingyan relates to an argument over a mathematical problem between two gods. The loser of this argument had his head cut off. However, when his head hit the ground, the earth would burn; if thrown in the sea, the water would dry up and if thrown in the air, it would explode in a fireball. To keep this from happening, seven goddesses took turns holding the head for a year each, changing over on Thingyan. The winner of the argument cut off the head of an elephant and stuck it on the headless body, thereby creating the god, Ganesh.
