In Jainism, pratikraman (pratikaman) is typically done in the evening after the day’s duties are over and around the time of Sandhya (twilight) or after sunset, before night prayers. The exact timing can vary slightly between traditions:

• Shwetambar: Usually performed after sunset and before going to bed, often as part of the evening Sandhya.
• Digambar: Also commonly done after sunset around the Sandhya period; some communities may do it a little earlier or later depending on local customs.

If you have a local guru or community guidance, follow their specific time for pratikraman.
