Dedicated Swadhyay Kaal timings show you the ideal periods during the day and night for studying Jain Agams and scriptures.
Navkarsi: The time when one can first consume food and water, exactly 48 minutes after sunrise. It is one of the most fundamental daily vows.
Porsi: One-fourth of the daytime. Observing a vow until Porsi is considered a higher level of discipline than Navkarsi.
Pratikraman: A ritual of introspection and seeking forgiveness. Done twice daily: at sunrise (Raysi) and at sunset (Devsi).
Choviyar: The practice of not consuming any food or water after sunset until Navkarsi the next morning, ensuring total ahimsa during nighttime.
Our tool calculates precise Navkarsi time, Pratikraman time, and other important Jain daily observance timings based on the sunrise at your exact location. Jain Pratikraman — the daily ritual of introspection and repentance — must be performed at a specific time relative to sunset, and this tool ensures you never miss the window.
The calculator covers all key Jain timings including Navkarsi (48 minutes after sunrise), Porsi, Sadhporsi, Raysi, and Devsi Pratikraman, plus Swadhyay Kaal. All timings are computed from the actual local sunrise for your city using precise astronomical data — not rough estimates — and automatically adjusts for Daylight Saving Time.
Search for any city worldwide to get today's Pratikraman time and a full monthly calendar for planning ahead. Our Jain prayer times calculator is trusted by the global Jain community for its accuracy and ease of use. Pair it with our sunrise & sunset tool for the underlying solar data.
