Hebrew Voices #154 – Reaping the Benefits of the Medieval Aviv Calendar: Part 1

In this episode of Hebrew Voices #154, Reaping the Benefits of the Medieval Aviv Calendar: Part 1, Nehemia speaks with a scholar at University College London about why Jews transitioned from sighting the new moon to a precalculated calendar, how Karaites remained faithful to sighting the New Moon, and the calendar controversies they confronted.

I look forward to reading your comments!

Nehemia, can you next interview scholars on the Dead Sea Sundial calendar?

You are correct your audience is very interested in the nuances of terminology.. at least this listener is 🙂

Call me a dumb American but to me the meaning of Aviv is when the Barley in the field is ready for Harvest as a whole not just a few grains that are ready for harvest because many will be premature. Many will be late but when will the majority of Barley will be ready. The Bible as a whole is full of mentions of “The Harvest”
