Mangala Gowri Vratam (fast) is observed in honor of Goddess Parvati, the consort of Lord Shiva. The fast is observed every Tuesday in the Hindu month of ‘Shravan’ (July-August). Parvati is regarded as the symbol of power and also embodies the virtues of a happily married woman. Observing the fast on this day is of deep religious significance for married women, who observe the ritual for a happy married life. Just as the Mondays of this month are auspicious for the worship of Lord Shiva, the Tuesdays are propitious for the veneration of Mangala Gauri (Avatar of Goddess Parvati).
Fasting is observed only by women and continues for 16 or 20 Tuesdays. Recently,married women observe the Mangala Gauri Puja for the first five years in almost every region of India.
