Holy Days
In the Bible, in addition to the Sabbath, the Holy Days are the three pilgrimage harvest festivals of Sukkot, Passover, and Shavuot; as well as the “Days of Awe,” the New Year and the Day of Atonement.
On all these Holy Days, including the Sabbath (Saturdays), work is forbidden. Many Jews who are not religiously observant will still connect with these days in a meaningful way through alternative practices.
There are other post-biblical festivals on which work is permitted, such as Chanukah and Purim. In all cases, Holy Days are marked by special synagogue services and celebrations in the home.
