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!
