“Pāṇī no kāl” (પાણીનો કાળ) means the time‑limit related to drinking water in Jain maryādā, mainly:

1. Day–night rule (Chauvihār)

- Water is to be taken only in daytime – after sunrise and before sunset. - From sunset till next sunrise, no water is taken (for one who observes chauvihār properly).

1. Boiled water time (Ukalelā pāṇī no kāl)

- Water is boiled and filtered to reduce hiṁsā of water‑bodied jīvas. - That boiled water is valid only for a limited time (“kāl”). - Many maryādās follow approx: - 24 hours during Cāturmās / Paryushan - 48 hours in the rest of the year - After that time is over, that water should not be used; fresh boiled water is prepared.

1. “Pāṇī no kāl today”

- The exact clock time today depends on: - Your city (sunrise/sunset timing) - Your sampradāy / guru‑maryādā (some keep 48 minutes before sunset as cut‑off, some at exact sunset). - For accurate today’s timing you should follow: - Your local Jain panchāng / tithi book / calendar app, or - The announcement of your local Jain Saṅgh / guru.

In simple practice for most śrāvaks:

• Drink only boiled, filtered water in the daytime.
• Stop water by sunset (or a little before it) and resume only after sunrise, according to your tradition.
