This is a three-day festival, celebrated by women also in honor of Parvati, in the month of Bhadrapad. By praying to Parvati on these three days, unmarried girls hope to get a husband like Shiva. Married women pray to her for marital bliss. According to Hindu mythology, Parvati was in love with Shiva. Being an ascetic however, Shiva was not aware of her. Parvati performed penance on the Himalayas for many years before Shiva finally noticed her.
Realizing the depth of her love and devotion, he agreed to marry her .Since then Parvati has been worshipped as Haritalika.
Women and young girls maintain nirjala vrata on these three days, and keep awake all three nights. This is symbolic of the penance which Parvati undertook to get Shiva as her husband. They offer food to Brahmins and young girls.
