How old was Enoch when he died?
Enoch lived 365 years, from 3382 BC to 3017 BC.
Enoch died at 365. The chart places his birth at 3382 BC and his death at 3017 BC, on the Ussher chronology it follows. Walked with God, and was not, for God took him. He did not die. (Gen. 5:18-24)
See it in context
A date means more beside its neighbours. The chart puts this answer in place next to everything happening around it — biblical and world history across the same six thousand years.
