Kathina Ceremony observed in Chittagong, Bangladesh
Kathina means Robe Offering Ceremony to Buddhist Monk. Kathina is a Buddhist festival which comes at the end of Vassa, the three-month rainy season retreat for Theravada Buddhists in Bangladesh (known as Kaṭhina Cībar Dān), Cambodia, Laos, Myanmar, Sri Lanka, India and Thailand. The season during which a monastery may hold Kathina is one month long, beginning after the full moon of the eleventh month in the Lunar calendar (usually October). It is a time of giving, for the laity to express gratitude to bhikkhus (Buddhist monks). Lay Buddhists bring donations to temples, especially new robes for the monks. In Sri Lanka offers Atapirikara අටපිරිකර (Eightfold Requisites).
