Pavarana is a Buddhist holy day celebrated on the full moon of the eleventh lunar month. It marks the end of the month of Vassa, sometimes called "Buddhist Lent." This day marks the end of the rainy season in some Asian countries like Thailand, where Theravada Buddhism is practiced. On this day, each monk (Pali: bhikkhu) must come before the community of monks (Sangha) and atone for an offense he may have committed during the Vassa.
