Vesak Day is a major Buddhist festival, as it celebrates the Birth, Enlightenment and Para nirvana (passing away) of the Buddha on the day of the first full moon in May, except in a leap year when the festival is held in June.
Kathina or Robe Offering Ceremony is the time of the year when the laity offers new robes and other requisites to the monks. Buddhist laypersons often give gifts to Buddhist monks but giving is also encouraged more generally, to one another and to good causes. Monks have a responsibility to share these with lay Buddhists through their examples and teachings. Giving of alms to monks is thought to benefit laypeople and to win them merits.
Kuan Yin’s (or Avalokitesvara) Birthday is a festival that celebrates the Bodhisattva ideal in the perfection of compassion in the Mahayana traditions of Tibet and China. It occurs on the 19th day of the 2nd, 6th and 9th month of the lunar calendar. Also, the Ullambana Offering held on the 15th day of the 7th lunar month is an important festival during which Buddhists practice filial piety to repay for the kindness of their parents.
