Answer

In Jain Dharma, the cycle of Chovisi—the 24 Tirthankars arising in each half-cycle of time—has been going on from beginningless time.

So it cannot be counted as a fixed number of years or Kalchakras.

Explanation

According to Jain cosmology:

• Time is eternal — it has no beginning and no end.
• Time continuously moves in two half-cycles:
  • Utsarpini — ascending time-cycle
  • Avasarpini — descending time-cycle
• In certain regions such as Bharat Kshetra and Airavat Kshetra, 24 Tirthankars appear in each Utsarpini and each Avasarpini.
• These 24 Tirthankars are called one Chovisi.

Because time itself is anadi-anant—beginningless and endless—there have already been infinite past Chovisis, and there will be infinite future Chovisis.

Spiritual Understanding

This teaches us that Jain Dharma does not see the universe as created at one point in time. Instead:

• The universe is eternal.
• Souls are eternal.
• Karma is beginningless.
• Tirthankars appear again and again to re-establish the path of liberation.

Takeaway

The cycle of Chovisis has not been going on for a countable number of years. In Jain tradition, it has been going on for infinite time and will continue for infinite future time.
