The best day of Adhikamas is full moon. The worship, chanting, penance and charity done on this day provides never-ending virtue. This year Adhikamas Purnima is on 31 May 2026.

Vat Purnima Vrat 2026 Date: Like Vat Savitri, the fast of Vat Purnima is also observed. The importance, worship method and story of both the fasts are similar. The only difference is that Savitra Vrat is observed on the new moon day of Jyeshtha month and Vat Purnima Vrat is observed on the full moon day of Jyeshtha month. Both the fasts are considered important for the husband’s long life and happy married life.

Vat Purnima fast is observed 15 days after Vat Savitri fast. The main reason for this is that in North India, Purnimanta lunar calendar is followed in the states including UP, Bihar, Madhya Pradesh, Haryana and Punjab. Whereas in other states the Amanta lunar calendar is followed. For this reason, in North India, Vat Savitri Vrat is observed 15 days before on Jyeshtha Amavasya and in other states, Vat Purnima Vrat is observed on Jyeshtha Purnima. Same rules, story and worship method are followed in both the fasts.
