Magha Puja Day refers to the veneration held on the full moon day of the 3rd lunar month to commemorate the occasion when the Lord Buddha delivered the Ovadapatimokkha (The Fundamental Teaching). Falling on the 15th day of the waxing moon of the 3rd month, this day is marked by a miraculous event where 1,250 of the Buddha’s disciples gathered to meet him at Veluvana Monastery in Rajgir, Magadha, without any prior appointment. All these monks were Arahants (Enlightened Ones) who had been personally ordained by the Buddha himself. On this day, the Buddha delivered the Ovadapatimokkha to the assembly, establishing the principles, ideals, and methods applicable to all societies. The core message can be summarized as: Refrain from all evil, cultivate all good, and purify the mind.
The Observance of Magha Puja in ThailandHistorically, the ceremony of Magha Puja was not practiced in Thailand until the reign of King Mongkut (Rama IV). His Majesty initiated the observance based on ancient scholarly traditions regarding the Magha-puranami (the full moon in the Magha constellation). This day honors the "Fourfold Assembly" (Chaturongkasannibat), the miraculous gathering of the Buddha’s disciples. Recognizing this as a significant marvel in Buddhism, scholars and the King established it as a day of worship to express faith in the Buddha and the Arahants.
Originally held only within the Grand Palace, the ceremony later expanded to the general public. Today, Buddhists nationwide participate by joining candlelight processions (Wien Thien) and making merit. Magha Puja typically falls on the full moon of the 3rd lunar month; however, during a leap year (Athikamat) with two 8th lunar months, the ceremony is moved to the full moon of the 4th lunar month.
