The public holiday for Buddha purnima in India was initiated by B. R. Ambedkar when he was the minister of law and justice. It is celebrated especially in Sikkim, Ladakh, Arunachal Pradesh, Bodh Gaya, various parts of North Bengal such as Kalimpong, Darjeeling, and Kurseong, and Maharashtra (where 77% of total Indian Buddhists live), as well as other parts of India as per Indian calendar. Buddhists go to common Viharas to observe a rather longer-than-usual, full-length Buddhist sutra, akin to a service. The dress code is pure white. Non-vegetarian food is normally avoided. Kheer, sweet rice porridge is commonly served to recall the story of Sujata, a maiden who, in Gautama Buddha's life, offered the Buddha a bowl of milk porridge. Informally called "Buddha's Birthday," it actually commemorates the birth, enlightenment (nirvāna), and death (Parinirvāna) of Gautama Buddha in the Theravada tradition. Tibetans in exile remember Buddha's birthday on the 7th day of the Saga Dawa month (fourth month of the Tibetan calendar), which culminates with Buddha's "parinirvana" celebrations on the full moon day.
