According to the Vedic calendar, the grand festival of Ganga Dussehra is celebrated every year on the tenth day of the Shukla Paksha (waxing phase) of the Jyeshtha month. This year, in 2026, the tenth day begins on the evening of May 24th and will continue until the afternoon of May 25th. Udaya Tithi has special significance in Sanatan Dharma, hence based on the rules of Udaya Tithi, Ganga bath, charity and special puja-archana will be done only on Monday, 25 May 2026.
