Answer

For 11 September 2026 in Surat, Navkarsi should be done approximately 48 minutes after sunrise.

I don’t have the verified sunrise time for Surat for that date in this chat, so I cannot give an exact Navkarsi time confidently.

Explanation

In Jain practice:

• Navkarsi = taking food/water only after sunrise plus about 48 minutes.
• So the calculation is:

Navkarsi time = Sunrise time in Surat on 11-Sep-2026 + 48 minutes

Takeaway

Please check the local Jain calendar/panchang for Surat sunrise on 11 September 2026, then add 48 minutes to get the correct Navkarsi time.
