No. The duration (even more than one year) does not by itself make a krodh, mān, māyā or lobh into anantānubandhi kaṣāya.

In Jain philosophy, anantānubandhi is defined mainly by intensity and effect, not by time:

• What is anantānubandhi kaṣāya?

The level of passion so intense that it: - Completely blocks/ destroys samyak‑darshan (right faith), and - Definitely leads to a narak gati (hellish birth) in future.

• Other three grades of the same four kaṣāyas:

1. Anantānubandhi – most intense, cuts off right faith. 2. Apratyākhyāna – obstructs taking major vows (mahāvrat). 3. Pratyākhyāna – obstructs higher renunciation, but milder than above. 4. Saṃjvalana – very slight; compatible with samyak‑darshan; remains even in high spiritual stages before keval‑jñān.

So:

• If someone keeps a mild anger or greed feeling for more than one year, it can still be only saṃjvalana or pratyākhyāna level.
• It becomes anantānubandhi only when:

- The passion is very intense and deep‑rooted, - It produces strong rāg–dveṣ, - And most importantly, it prevents or destroys right faith and surely results in hellish karma bondage.

Both Digambar and Śvetāmbara agree on these four intensities of each kaṣāya; they differ slightly in technical details and stage‑descriptions, but none say “if it lasts 1 year, it automatically becomes anantānubandhi.”

In practice, any long‑lasting kaṣāya (even if not fully anantānubandhi) is still very dangerous, so Jain āchāryas strongly advise continuous efforts: pratikramaṇ, kṣamā (forgiveness), vinay (humility), svādhyāy and dhyān to weaken it as early as possible.
