Shabbat or Shabbos (Sabbath in English) is a day reserved for rest, prayer, and celebration.
Remembering and keeping Shabbat is one of the Ten Commandments.
Jews observe Shabbat from Friday night to Saturday night. Shabbat is observed in many different ways.
Some Jews observe the laws of Shabbat very closely. Some enjoy a meal with family and friends. Some go to the synagogue on Friday night and/or Saturday morning.
A ceremony called Havdalah marks the end of Shabbat and the start of a new week.
Christianity and Islam also have a tradition of a designated day of rest or prayer set aside every week. In the creation story of the book of Genesis, G-d creates the world in six days and rests on the seventh.
