Chauvihār (also spelled Chovyaar) time is from your local sunset today until sunrise tomorrow. During this period, you should not take any food or water.

How to get today’s exact time

• Check today’s local sunset for your city and finish your last sip a few minutes before that time.
• Resume water only after sunrise.

Tradition notes

• Digambar: No water after sunset; daytime water should be boiled and filtered.
• Shvetāmbara (Derāvāsī/Sthānakvāsī/Terāpanthī): Same rule in practice—no water after sunset; daytime water should be filtered, and many take only boiled water.
