“Sathpaursi” / “Porsi” timings are not fixed by the clock. They depend on:

• today’s sunrise and sunset at your city, and
• the Jain panchang (to mark the correct tithi and porsi period).

Because of this, I cannot tell you the exact time for “Sathpaursi today” without your location and the local panchang.

General guidance (both traditions use the same principle, though small details may differ by gacch/sampraday):

• Porsi is a day-time observance (linked to sunrise, not to the 12‑hour clock).
• The allowed eating period is decided by the panchang, usually starting some time after sunrise and ending before a certain cut‑off before sunset.
• For strict observance, you should:

- Ask your local Jain temple / guru / panchang for “aaj ni Sath Porsi ni waqt”. - Or check a Jain panchang app/website set to your exact city and tradition (Śvetāmbara / Digambara).

To follow the vow properly and without doubt, always go by the local Jain panchang and guru’s instruction for today’s timing.
