Shabbat (Hebrew: שַׁבָּת, shabbāt; Yiddish שאבעס, shabbos; "rest" or "cessation") is the seventh day of the Jewish week and a day of rest in Judaism. Shabbat is observed from sundown Friday until the appearance of three stars in the sky on Saturday night. The exact time, therefore, differs from week to week and from place to place, depending on the time of sunset at each location.
