Saga Dawa Düchen commemorates the birth, enlightenment, and parinirvana of Buddha Shakyamuni and  the month of Saga Dawa is the most important month in the Tibetan lunar calendar. Saga Dawa, the 4th lunar month, runs from May 12, 2021 until June 10, 2021. The 15th day of this lunar month, the full moon day, is called Saga Dawa Düchen (Düchen means “great occasion”). In 2021, Saga Dawa Düchen falls on Wednesday, May 26th.    Saga Dawa is known as the month of merits, and is also sometimes called bumgyur dawa, which means “merits multiplied by a hundred thousand times.”  Thus any practice or activity one does is said to be multiplied by a hundred thousand times (or more), and so Buddhists take advantage of this occasion to do practice and say prayers to benefit all sentient beings.
