Vat Savitri Vrat is a significant Hindu fasting day observed by married women for the well-being and longevity of their husbands. This vrat is dedicated to Goddess Savitri, who is considered to be the epitome of wifely devotion and loyalty.

On this day, women fast from sunrise to sunset and pray for the good health and prosperity of their husbands. The fast is observed for three consecutive years, with rituals performed under a banyan tree, representing the strong bond between the husband and wife.

The Vat Savitri Vrat is based on the story of Savitri and Satyavan from the epic Mahabharata, where Savitri's unwavering love and dedication to her husband compelled Yama, the god of death, to grant her husband back to life. The fast is believed to bring blessings and protection to the married couple's relationship.
