Answer

Yes, you can do Devasīya Paryushan Pratikraman at 8 PM if that is the practical time available to you.

Explanation

Traditionally, Devasīya Pratikraman is done in the evening, after the day’s activities, to reflect on and repent for faults committed during the day.

During Paryushan, Pratikraman is especially important, so it is better to do it sincerely than to skip it because the ideal timing was missed.

If your sangh, guru, or family follows a specific timing, it is best to follow that discipline. But if circumstances require, doing it at 8 PM with proper bhāv, focus, and humility is acceptable.

Spiritual Understanding

The main purpose of Pratikraman is:

• Ātma-chintan — self-reflection
• Ālochana — confession of faults
• Pratikraman — turning back from wrong conduct
• Pratyākhyān — resolving not to repeat mistakes
• Kṣamā — seeking forgiveness

The purity of your intention matters greatly.

Takeaway

If 8 PM is the time you can do it properly, do it with sincerity, concentration, and repentance. It is better to do Pratikraman late with devotion than not do it at all.
