Answer

To calculate Porsi in Jain practice, count 3 hours from local sunrise.

Explanation

Commonly used Jain time divisions are:

• Porsi = about 3 hours after sunrise
• Sadhporsi = about 4.5 hours after sunrise
• Purimaddha = about 6 hours after sunrise

So the basic formula is:

• Porsi time = Sunrise + 3 hours

Example: If sunrise is at 6:00 AM, then:

• Porsi = 9:00 AM
• Sadhporsi = 10:30 AM
• Purimaddha = 12:00 PM

Spiritual Understanding

In Jain Dharma, these timings are used to maintain discipline, simplicity, and awareness in food practice. The purpose is not only timing, but also self-restraint and observance of proper conduct.

Takeaway

For most practical purposes, remember:

Porsi = sunrise + 3 hours

If you want, I can also give you a simple chart for Porsi, Sadhporsi, and Purimaddha based on any sunrise time.
