For Chauvihār (Chauvihaar) / Chaivihar, the Jain rule is:

• Stop taking food at least 48 minutes (1 gharī) before local sunset.
• Water (for those who follow strict Paushadh/fasting rules) is also usually stopped by that time, depending on your vrat and tradition.

To tell you the exact time for today, I need your city and country (for example: “Mumbai, India” or “Chicago, USA”), because sunset time changes by place and date.

Please reply with your location, and I’ll tell you today’s Chaivihar time based on the Jain rule (sunset minus 48 minutes).
