About
Rath Yatra falls on the second tithi of the bright half of Ashadha, in June or July. Jagannath, Balabhadra and Subhadra are drawn on three chariots from the Puri temple to the Gundicha temple, where they stay for a week before the return journey (Bahuda Yatra) on Dashami. The tithi at sunrise fixes the day, and the Puri temple's own almanac is the final authority for the hour of pulling. Ahmedabad, Kolkata and ISKCON centres hold their own processions on the same day.
How it is observed
Pulling the chariots by rope, darshan of the deities on the chariot, and the Gajapati king's ritual sweeping (chhera pahanra).
