In Jainism, the concept of "kaal" (time limit) for flour (atta) is very important due to the principle of ahimsa (non-violence) and the desire to minimize the harm to microorganisms. According to Jain dietary rules, freshly ground flour should ideally be used within a limited time frame to avoid the growth of new life forms (such as bacteria or insects) in the flour, which may occur as it sits.

Traditional Guidance:

• Many Jain households and sects (such as Sthanakavasi and Terapanthi) observe a "kaal" of 24 hours for flour. This means flour should be used within 24 hours of grinding.
• Some stricter practices recommend using the flour on the same day it is ground.
• During the four months of Chaturmas (rainy season), the rules may be even more stringent, and some may prefer to use flour within a few hours.
• Leftover or stored flour is generally avoided, as it is believed that micro-organisms begin to develop after some time, increasing the risk of himsa (violence to minute life forms).

Summary Table:

| Occasion/Season | Kaal for Flour | |----------------------|------------------------| | Regular Days | Within 24 hours | | Chaturmas (rainy) | As soon as possible, ideally within a few hours | | Some Sects/Strict | Same day |

Note: Different families and sects may have slight variations in practice, so it is always best to follow the guidance of one's tradition or consult a Jain monk (Sadhu/Sadhvi) for specific details.

Reasoning: Using flour within this limited time helps minimize the violence towards tiny living beings that may develop in stored food.
