To know the correct Chauvihār (chovihar) time for 2 December 2025, we need two important details:

1. City and country you will be in on that date
2. Tradition / rule you are following, for example:

- Many Jains take Chauvihār as no food or water after sunset. - Some follow Samayik-based timings or specific mandir panchāng timings.

Chauvihār time is usually calculated from the local sunset time (sometimes with a small safety margin like a few minutes before sunset), and sunset varies by city and date.

Please reply with:

• Your city (and country) for 2 December 2025
• If you follow any specific Jain panchāng/derāsar rules (if you know)

Then I can give you the approximate Chauvihār cut‑off time for that date and place.
