Shabbat [SEP] Introduction
Shabbat ( or ; , "rest" or "cessation"), Shabbos (, Ashkenazi Hebrew and ), or the Sabbath, is Judaism's day of rest on the seventh day of the week—i.e., Saturday. On this day, religious Jews remember the biblical story describing the creation of the heavens and the earth in six days and look forward to a future Messianic Age. Since the Jewish religious calendar counts days from sunset to sunset, Shabbat begins in the evening of what on the secular calendar is Friday. Shabbat observance entails refraining from work activities, often with great rigor, and engaging in restful activities to honour the day.
