Answer

If you are doing Chauvihar, you should finish eating and drinking before sunset. After sunset, no food or water is taken until sunrise.

Explanation

In Jain practice, Chauvihar means:

• No food after sunset
• No water after sunset
• Resume only after sunrise

So the important rule is not a fixed clock time, but the actual time of sunset in your location.

Spiritual Understanding

Chauvihar helps in:

• Practicing discipline
• Reducing हिंसा in daily life
• Supporting purity of conduct
• Strengthening self-control and awareness

It is considered a meaningful observance in Jain life.

Takeaway

Eat your last meal and drink water before sunset. If you want, I can also explain the difference between Chauvihar, Tivihar, and Aayambil.
