Madhu Purnima (Bangla for 'honey full-moon') is a Buddhist festival celebrated in India and Bangladesh, especially in the region of Chittagong. It occurs on the day of the full moon in the month of Bhadro (August/September).
The day commemorates an occasion on which the Buddha retreated to the wilderness of Parileyya forest to bring peace between two quarrelling factions of disciples. According to legend, a monkey and an elephant named Parileyyaka fed him during this time, the elephant bringing fruit and the monkey bringing a honeycomb. The monkey was so excited when the Buddha accepted his gift that he began leaping from tree to tree and fell to his death. However, he was immediately reborn in Tavatimsa as a result of his generosity.
Madhu Purnima is celebrated as a joyous day of unity and charity. Indian and Bangladeshi Buddhists observe it by bringing gifts of honey and fruit to monasteries.
