• In Jain cosmology, the descending half-cycle is called Avasarpini, and it is divided into six eras (āra). The 5th āra is called Duṣamā, and its total duration is 21,000 years. This is the period we are said to be in now. However, there is no single universally fixed statement in all texts about exactly how many of those 21,000 years have already elapsed; various traditional accounts give different approximate readings, and some narrations even offer rough current-time estimates. The important point is that the 5th āra lasts 21,000 years, and we are within that span. ( jainpedia.org)
