In Jainism, kaal refers to the time limit within which flour should be used after grinding. The aim is to minimize harm to tiny living beings that may be present in stored flour.

• Common practice: many Jain households observe a 24-hour kaal for flour (atta) — use the freshly ground flour within 24 hours.
• Variations: some communities prefer to use flour on the same day, and during the Chaturmas (rainy season) rules may be stricter.
• Always follow your tradition: different Jain sects and families may have slightly different guidelines, so check with your local Jain monk or your own tradition for the exact rule you should follow.
