Answer

Paryushan generally starts on:

• Shwetambar Jain tradition: Bhadarva Vad 12 and ends on Samvatsari.
• Digambar Jain tradition: Das Lakshan Parva usually begins after Samvatsari, from Bhadarva Sud 5 to Bhadarva Sud 14.

Explanation

The exact calendar date changes every year because Jain festivals follow the lunar calendar.

If you are asking for a specific year, please tell me the year and your tradition — Shwetambar or Digambar — and I can answer more clearly if it is established in the Jain calendar.
