In Jain daily conduct, these words indicate “when” you take your first food or drink, counted from local sunrise.

• Porsi: taking food/drink 1 porsi after sunrise, i.e., 3 hours after sunrise.
• Sadh Porsi (often heard as “sath porisi”): taking food/drink 1.5 porsi after sunrise, i.e., 4 hours 30 minutes after sunrise.

Example: If sunrise is at 6:00 AM

• Porsi time = 9:00 AM
• Sadh Porsi time = 10:30 AM

Use: Jains take a pachchakkhan (vow) such as “Today I will eat at Porsi/Sadh Porsi,” as a form of aahar-sanyam (restraint in food), mindfulness, and discipline.

Notes by tradition:

• Shvetambar: These terms are widely used exactly as above.
• Digambar: The practice of fixing eating-times from sunrise is also followed, though local terms and emphasis may vary; always follow your own sangh/guru’s guidance.

Always calculate from the actual sunrise at your location for that day.
