Answer

In Jain practice, during Tivihar, water may be taken only until sunset.

After sunset, water is not taken.

Explanation

Tivihar means avoiding three types of intake after sunset:

• Food
• Water
• Other edible/drinkable items

So if a person has taken a Tivihar pachchakkhan, they may drink water before sunset, but not after sunset.

In many Jain families and sanghs, people stop slightly before the actual sunset time to be safe.

Takeaway

For Tivihar, water should be taken before sunset. After sunset, one observes restraint from water as part of the vow.
