It's Rosh Chodesh, the beginning of a new month in the Jewish calendar! In celebration of this monthly event, a family goes out to the Negev Desert to camp out and observe the moon. An essay about the changing phases of the moon and their relationship to the Jewish calendar, this audiobook explains the basics of the Jewish calendar, which is based on the moon rather than the sun. Instructions for building a papier mache moon are included. This audiobook is the fifth in Kar-Ben's Nature in Israel holiday series.
