Answer

Yes, you can do Sanvatsari Pratikraman at 08:00 pm if you were not able to do it earlier.

Explanation

Traditionally, Sanvatsari Pratikraman is done on the day of Sanvatsari, usually in the evening, according to the proper time followed by one’s Jain tradition, sangh, or local upashray/derasar.

If due to circumstances you can only do it at 8:00 pm, it is still spiritually meaningful to do it with:

• Faith
• Repentance for mistakes
• Humility
• Forgiveness toward all living beings
• A sincere feeling of “Micchami Dukkadam”

Spiritual Understanding

The heart of Sanvatsari Pratikraman is not merely the clock time, but sincere pratikraman — turning back from wrong conduct, asking forgiveness, and resolving to live with more awareness and non-violence.

Takeaway

If 8:00 pm is the time available to you, do Sanvatsari Pratikraman respectfully and sincerely. If possible, also follow the guidance of your local Jain sangh, guru, or tradition.
