Vat Purnima or Wat Purnima (वट पूर्णिमा vaṭapūrṇimā "Banyan tree full moon") is a celebration observed in the Western Indian states of Gujarat, Maharashtra, and Karnataka, India. Purnima means "full moon" and is celebrated on the full moon day (the 15th) of the month of Jyeshtha on the Hindu calendar, which falls in June on the Gregorian calendar. In 2016 Vat Purnima is on June 19th. Women pray for the prosperity and longevity of their husbands by tying threads around a banyan tree or waṭ, which is called "pipal puja", on this day. It honours Savitri, the legendary wife who rescued her husband's soul from the ruler of the departed, Yama.
