CJ Classics: The Jewish Calendar

Each December we are faced with the question, when do we start saying ותן טל ומטר? The answer can be found in the first of these classic CJ articles about the Jewish calendar.

• The Strange Case of December 4 by Arnold and Daniel Lasker, Fall 1985 (Vol. 38 No. 1)
• The Counting of Day and Night by Meir Ydit, Fall 1981 (Vo. 35 No. 1). An exploration of why "ויהי ערב, ויהי בקר" is not, in fact, the origin of the custom of Jewish "days" beginning in the evening.
• Behold, A Moon is Born: How the Jewish Calendar Works by Arnold and Daniel Lasker, Summer 1989 (Vol. 41 No. 4). An advanced look at the inner workings of the Jewish calendar, specifically how to calculate the מולד.
