Please explain about ara, we are in which ara now

In Jainism, the term “ara” is not a standard, widely used technical word for a fixed time-period across all texts. Jain cosmology does discuss cycles of time and eras, but the word “ara” by itself isn’t a fixed category that is universally applied in Digambar and Śvetāmbara literature in the way some other terms are.

What you might be encountering

• It could be a regional or manuscript-specific way of saying “era/period” (time division) within a local calendar or commentary.
• It might be a misreading or a shortened form of another term used in a particular text.

If you can share the exact line or the source where you saw “ara” (the text, author, or tradition), I can explain its meaning precisely according to Jain sources and, if relevant, note any difference between Digambara and Śvetāmbara interpretations.
