Answer

For a Jain upvas, the time until which you can drink water depends on your tradition and the rule you have taken:

• Chauvihar upvas: No food or water after sunset of the previous evening, and no water during the upvas day.
• Tivihar upvas: No food, but boiled water may be taken during the permitted daytime period.

If you are doing Tivihar upvas, boiled water is generally taken only during daylight, and you should stop before sunset according to your local place.

Explanation

Today is September 10, 2026. I do not know your city, so I cannot give the exact sunset-based cutoff time.

In Jain practice, the safe guidance is:

• Drink only boiled and cooled water, if your upvas allows water.
• Stop before sunset.
• Follow the rule given by your family, guru, upashray, or sangh.

Takeaway

If your upvas is Chauvihar, do not drink water today. If it is Tivihar, you may drink boiled water until before your local sunset.
