For Ratlam, today (16 March 2026), sunrise is around 6:39 am (IST).

According to Jain maryada, Porsi (1‑porsi) is 3 hours after sunrise, so:

> Porsi time today in Ratlam ≈ 9:39 am IST

This means if you are doing 1‑porsi, you should take food/water only after 9:39 am (and before your next cutoff like sadh‑porsi, etc., as per your pachchakkhan).
