This poya day is usually celebrated on the first full moon in February.
It commemorates the appointment of Arahath Sariputta (Sariyuth) and Arahath Moggallana (Mugalan) as the two Chief Disciples (Agrashavakas) of the Gautama Buddha.
Navam Poya also commemorates the first Buddhist Council, held three months after the Parinirvana of the Buddha.
Navam Poya is also believed to be the day on which the Buddha announced his Parinirvana, that was to come in three months.
