Gujarati
नाग पांचम · નાગ પાંચમ
The Gujarati Nag Pancham, serpent worship on Shravan Krishna Panchami (Gujarati calendar), three days before Janmashtami.
Astika stopped Janamejaya's snake sacrifice on this day, sparing the serpent race. Separately, Krishna subdued Kaliya in the Yamuna and spared him.
Milk offered at snake images, anthills and Naga stones. Snakes are not disturbed, and digging and ploughing are avoided on the day so as not to harm anything underground. Images of nagas are drawn at doorways.
Milk and rice offerings. In Maharashtra, deep-fried nothing, frying and roasting are avoided, since the hearth is associated with the serpent. Steamed dishes instead.
Gujarat's date differs as above. In South India, particularly Karnataka, women worship at Naga stones for the wellbeing of brothers. In Bengal it's Manasa Puja, for the snake goddess Manasa.
