ha! It may be in the Bible, but Jubilee was never celebrated, not even once.

Whether or not it happened exactly as described within the Torah/Bible, we have plenty of records to indicate ancient societies regularly overturned debts.

> Jubilee was never celebrated

Ancient societies of all stripes had periodic debt forgiveness. Ancient (pre-Christian) Rome, for example.
