Navkarsi time is not fixed to a clock time. It is observed about 48 minutes after local sunrise. So tomorrow (December 2, 2025) in Mumbai, you will start Navkarsi roughly 48 minutes after sunrise in Mumbai on that date. Since sunrise times vary a bit by day, the exact minute can shift a little.

• Rule: Navkarsi begins about 48 minutes after local sunrise; some sanghs may use a very small local variation, but 48 minutes after sunrise is the standard guideline. For precise timing, check your local temple or Panchang. You can read more here .

Note: If you’re coordinating with a Jain sangh or bhojanshala, they may publish a specific window for Navkarsi that day, so follow that local schedule.
