Answer

“Pakkhi” dates depend on the Jain lunar calendar, your location, and the Jain tradition/calendar being followed.

For this month, I should not guess the exact Pakkhi date without a verified Jain Panchang.

Explanation

In Jain practice, Pakkhi Pratikraman is generally observed on the 14th day of each fortnight:

• Sud Chaudas — 14th day of the bright fortnight
• Vad Chaudas — 14th day of the dark fortnight

Because tithi timings can vary by place, the date may differ depending on where you live.

Takeaway

Please check your local Jain Sangh Panchang or Jain temple calendar for the exact Pakkhi date in your city.
