Janmashtami is a Hindu festival that celebrates the birth of Lord Krishna, who is considered the eighth avatar of Vishnu. It usually falls in August or September, on the eighth day of the dark fortnight in the month of Bhadrapada. Devotees observe fasting, sing devotional songs, and participate in various cultural activities to honor Lord Krishna. The festival is marked by night-long vigils, where people reenact scenes from Krishna's life, including his childhood exploits. In many regions, particularly in Mathura and Vrindavan, grand celebrations take place, featuring dance, music, and the breaking of clay pots filled with curd, symbolizing Krishna's playful nature.
