The festival of Amay Gyan is held each year on the 13th and 14th waning days of the month of Nayon of the Burmese calendar (May or June), in Ayegyigon, Mandalay Region.

[1] Amay Gyan was born Chan-Tha to the chief of the Shwedaung village in present-day central Myanmar in c. mid-14th century.

Her family reportedly disowned her for marrying Nga Tet Pya, whom her father deemed a dubious character and a drunkard.

One day, a drunken Chan-Tha argued with the guards at one of the gates of Ava, the capital.

The argument quickly escalated into a physical altercation after she started cursing out at the guards.
