How soon after death should Asthi Visarjan be performed?

Hindu tradition recommends performing Asthi Visarjan as early as possible — ideally within the first year after death. The ashes should be collected on the 1st, 4th, 7th, or 9th day after cremation. If circumstances prevented earlier immersion, the ritual can still be performed years later and remains fully valid. Do not let the passage of time stop you from fulfilling this duty.
