Answer

Today in Surat, Chovihar should be done before sunset.

For Saturday, September 12, 2026, Surat sunset is around 6:40 PM IST. So it is best to complete Chovihar by about 6:25–6:30 PM IST to keep a safe margin.

Note

Chovihar means avoiding all food and water after sunset, so one should finish eating and drinking before sunset. Since exact sunset can vary slightly by location and panchang, please confirm with your local Jain panchang or sangh if you need the exact ritual time.
