Somvati Amavasya, a significant day in Sanatan Dharma for honoring ancestors, falls on June 15, 2026. This powerful New Moon day, occurring on a Monday, is ideal for spiritual cleansing, performing rituals like Pitru Tarpan, and engaging in charitable acts. Devotees often practice Ganga Snan and feed cows and crows, believed to be messengers of ancestors.
