Answer

For the Sthānakvāsī Jain tradition, Paryushan usually starts on Bhādrapad Vad 5 and ends with Samvatsari on Bhādrapad Vad 14.

However, the exact English calendar date changes every year according to the Jain lunar calendar.

Takeaway

Please check your local Sthānakvāsī Jain Sangh calendar for the exact date in your city, because the date may vary slightly based on local Panchang and Sangh tradition.
