Answer

No. In a Tivihar Upvas, one does not eat food and also does not drink water before sunrise or after sunset.

Water is allowed only during the permitted daytime period, generally after sunrise and before sunset, according to one’s tradition and guidance.

Explanation

In Jain practice:

• Chauvihar Upvas means no food and no water for the full fast period.
• Tivihar Upvas means no food, but boiled/filtered water may be taken during the allowed daytime period.

So if it is after sunrise, drinking water before 11am is generally allowed in Tivihar Upvas. If it is before sunrise, it is not allowed.

Takeaway

In Tivihar Upvas, water is allowed during the day, but not at night. For exact timing, follow your family, sangh, or guru’s maryada.
