In a Jain calendar, kaal means time or a time-period.

In Jain Dharma, time is understood in a very broad sense:

• very small units of time, and
• very large cosmic cycles of time.

So, kaal can refer to:

1. Daily time divisions used in practice and rituals
2. Seasonal or calendar time
3. Cosmic time cycles like:

- Utsarpini Kaal — an ascending period - Avasarpini Kaal — a descending period

In simple words, kaal is the measure of time in Jain understanding, from a moment to an entire cosmic era.

If you want, I can also explain Jain time divisions like samay, avali, muhurta, and kaalchakra.
