In Jainism, Chauvihar (chovihar) refers to refraining from eating and drinking (including water) after sunset until sunrise the next day. The exact time for chovihar is determined by the local sunset time in your area. Traditionally, Jains stop consuming food and water about 48 minutes (one muhurt) before actual sunset, as a precaution and to ensure strict observance of ahimsa (non-violence towards micro-organisms that may increase after dark).

To find the chovihar time for today, please check the local sunset time in your city and subtract approximately 48 minutes from it. That will be the recommended latest time to finish any food or water for chovihar.
