Kason is the second Myanmar month and comes in April-May. It is a sacred month for Myanmar Buddhists.

The full-moon day of Kason was the day hermit Sumeda heard from Dipankara that he would one day be a Lord Buddha, the day embryo-Gautama Buddha was born, the day he saw Four Noble Truths; the day Maha Bodhi Tree grew for him and the day of his Pari-Nibbana.

So, this day is commemorated by Myanmar Buddhists as Buddha Day.

The main activity on this festival day is pouring water at the ‘Bo’ (Bodhi Nyaung) tree.

From days of yore to this day, Bo tree watering ceremonies are held at numerous pagodas in the country on this day.

It is one of the traditional cultural festivals of Myanmar people.
