Can pratikaman done after 9 PM and before 12 PM at night of shwetambar purtipujak
Yes. In Śvetāmbara Jain practice, Pratikraman (pratikaman) is commonly done in the evening, after sunset. The traditional guideline is roughly 48 minutes after sunset, but the exact time can vary with local sunset times and temple schedules. So doing Pratikaman after 9 PM and before midnight on Purti-pujan night is generally acceptable if it falls within the evening Pratikraman window observed by your sangh. Always check your local temple or community timing for the محدद slot. You can read more here
