Today (Feb. 12) marks the Navam Full Moon Day.
It was on a Navam Full Moon where the Gautama Buddha appointed Arahats Sariputta (Sariyuth) and Moggallana (Mugalan) as the first two chief disciples (Aggasavakes).
Promulgation of pre-liberation or collection of precepts of Vinaya or discipline and the determination of the term of life of the enlightened one by Gautama Buddha are also significant events associated with Navam Full Moon Poya Day.
