Answer

For Mumbai today — Monday, October 12, 2026:

Chovihar should be done before sunset.

Approximate sunset in Mumbai today is around 6:20 PM, so it is best to complete Chovihar before 6:15 PM.

Note

In Jain practice, Chovihar means avoiding food and water after sunset until the next morning. Many people keep a small safety margin before sunset to avoid accidental delay.
