Answer

In Jain practice, Chovihar ends after sunrise, when one takes the first permitted food or drink after doing proper morning discipline.

If someone does not want to do Navkarshi, then they should still wait until sunrise before ending Chovihar.

Explanation

• Chovihar means not eating or drinking after sunset.
• It is generally continued until the next morning after sunrise.
• Navkarshi means eating/drinking after a certain period after sunrise, traditionally about 48 minutes after sunrise.

So:

• If doing Navkarshi: end Chovihar about 48 minutes after sunrise.
• If not doing Navkarshi: end Chovihar after sunrise.

Takeaway

Chovihar should not be ended before sunrise. Navkarshi is a higher discipline, but the basic ending of Chovihar is after sunrise.
