Answer

8 September 2025 falls around Bhadrapad month in the Jain calendar.

However, the exact Jain tithi depends on:

• Your location
• Sunrise time
• Whether you follow the Jain calendar tradition used in your region

So I should not give an exact tithi without a verified Jain Panchang.

Takeaway

For the exact Jain tithi of 8 September 2025, please check a reliable Jain Panchang for your city or region.
