How many days after death should Asthi Visarjan be performed?

The ideal window for Asthi Visarjan is within 10 days of cremation, before the Dasha Karma ceremony, as prescribed in the Antyakarmadipaka and related smriti texts. Bone collection itself should happen on the 2nd day, the 3rd day, or as soon as the pyre has completely cooled. If immersion within 10 days is impossible due to travel, weather, or other constraints, the ritual remains valid if performed later — within 3 months, within a year, or even after several years. When significantly delayed, the ceremony is often combined with Shraddha and Pind Daan to restore spiritual balance for the departed soul.
