Hindus observe Nirjala Ekadashi on June 25, 2026, a highly auspicious day dedicated to Lord Vishnu. This strict fast, observed without food or water until the next day, is believed to bestow the benefits of all 24 Ekadashis and cleanse past sins. Devotees engage in prayers, donations, and chanting, with the fast breaking on Dwadashi after specific rituals. Health precautions are advised due to the summer observance.
