The Buddha Unfolding Festival is celebrated from the 14th to the 16th in the fifth Tibetan month.

The Buddha Unfolding Festival is an important religious activity at the Tashilhunpo Monastery involving scripture chanting, prayers for rain, along with a joyous festival for people. Giant Thangkas of Amitayus, Sakyamuni and Maitreya are displayed on the monastery's Thangka Wall, and thousands of pilgrims rush to the monastery to pay their offerings to the Buddhas and accumulate merits.

The tradition has lasted for 500 years.
