Answer

In Jain tradition, there is no equal fixed time gap between all 24 Tirthankaras.

The 24 Tirthankaras of the current Avasarpini cycle appeared over an extremely vast span of time. Their lifetimes and gaps were not uniform.

Explanation

A simple way to understand it:

• The first Tirthankaras appeared in the very ancient past.
• The middle Tirthankaras were separated by long and varying intervals.
• The 23rd Tirthankara, Shri Parshvanath, and the 24th Tirthankara, Shri Mahavir Swami, are the most recent ones.
• In traditional Jain understanding, Parshvanath lived about 250 years before Mahavir Swami.

So, if you mean the time span between each Tirthankara, there is no single standard number for all of them.

If you mean the overall span covering all 24 Tirthankaras, it extends across a very long portion of the current time cycle, not a small historical period.

Spiritual Understanding

The purpose of the Tirthankaras is not only historical chronology, but the teaching of:

• right faith
• right knowledge
• right conduct
• liberation from karma

Their appearances remind us that Dharma arises again and again in the world, according to the rhythm of time.

Takeaway

The 24 Tirthankaras did not appear at equal intervals. Their appearance spans a vast cosmic time cycle, with varying gaps between them.
