Snana Yatra (also known as Debasnan Purnima) is the majestic ceremonial bathing festival of Lord Jagannath, Lord Balabhadra, Devi Subhadra, and Sudarshana at the 12th-century Srimandir in Puri, Odisha. Celebrated on the full moon day (Purnima) of the Hindu lunar month of Jyestha (typically May or June), it marks the official birthday of Lord Jagannath.
It is the first major public event in the legendary annual Ratha Yatra cycle. On this day, the sacred deities step out of the inner sanctum (Garbhagriha) to a raised platform called the Snana Mandap, allowing devotees from all walks of life—regardless of caste or creed—to view the Lords directly.
Mythological Origin & Significance
According to the Skanda Purana, King Indradyumna, who originally installed the wooden deities in Puri, performed the first grand ceremonial bath on this full moon day.

Devotees believe that a single glimpse (Darshan) of Lord Jagannath on the Snana Mandap cleanses a person of all sins, giving rise to the famous Odia proverb: “Gundicha Mandapam Yanti Ye Bhaktaya Muditanvita, Te Samastam Papani Mukta Yanti Harer Padam.”
