Wesak Day is a Buddhist festival that commemorates three important events in the life of the Buddha: his birth, enlightenment, and death. It is celebrated on the full moon of the lunar month of May and involves gatherings at temples for prayer, offerings, and listening to teachings. While Muslims cannot participate in the religious ceremonies, they are permitted to attend public celebrations if they do not involve practices contrary to Islam like idol worship. The Islamic view is that Muslims should not imitate the festivals and rituals of other religions.
