Calendar of the Sadducees

Did you know the Sadducees always wanted to have Shavuot on Sunday? Join Rabbi David Sedley and examine the Sadducee calendar, including how the rabbinic and Sadducee calendars represented two entirely different worldviews.

Calendar of the Sadducees: Calendar of the Saducees
Class description

In this class we look at the evolution of the Jewish calendar, from the earliest times when witnesses would testify they had seen the new moon, to later when the rabbis calculated the orbit of the moon and the testimony was purely logistical, to the end of rabbinic authority and the fixed calendar. The transmission of the calendar also changed from virtually instantaneous bonfires to sending messengers — which created the second day of festivals outside Israel.

We look at why the Sadducees were so keen to mess with the calendar — why did they want Shavuot on Sunday?

We also look at different ways of counting the year — from the Exodus, from the reign of kings, from the Seleucid era and finally from creation.

And we end by learning how the rabbis decide the calendar, not Heaven.
