Vassa
Vassa (Pali: vassa-, Sanskrit: varṣa-, both "rain") is the three-month annual retreat observed by Theravada Buddhists. Taking place during the wet season, Vassa lasts for three lunar months, usually from July (the Burmese month of Waso, ဝါဆို) to October (the Burmese month of Thadingyut, သီတင်းကျွတ်).
