The Myanmar month of Waso is the beginning of the monsoon rains. It is also the start of the Buddhist Lent. Monks are prohibited to travel overnight from their monasteries. According to the monks' code of conduct, they are still obligated to make the rounds for their daily food whether it is raining or not. As it is, they need spare robes. Therefore there is a ceremony to offer robes to the monks for use during the wet season.
