Short answer: About 18,400–18,500 years are left in the current āra.

Details:

• Jain tradition says we are in the 5th āra (Pañcam āra, Duḥṣamā) of the current Avasarpiṇī, and this āra lasts 21,000 years.
• Shvetāmbara reckoning: Mahāvīra’s nirvāṇa is placed in 527 BCE, and the 5th āra begins shortly after. As of August 24, 2025, roughly 2,548 years have elapsed, so about 21,000 − 2,548 ≈ 18,452 years remain.
• Digambara reckoning: Mahāvīra’s nirvāṇa is placed in 468 BCE (5th āra beginning shortly after). As of August 24, 2025, roughly 2,489 years have elapsed, so about 21,000 − 2,489 ≈ 18,511 years remain.

So, depending on the tradition followed, approximately 18,450–18,510 years are left in this 5th āra.
