what is the definition of sabbath in hebrew
Shabbat Shabbat (/ʃəˈbɑːt/; Hebrew: שַׁבָּת‎ [ʃa'bat], "rest" or "cessation") or Shabbos (['ʃa.bəs], Ashkenazi Hebrew and Yiddish: שבת‎), or the Sabbath is Judaism's day of rest and seventh day of the week, on which religious Jews, Samaritans and certain Christians (such as Seventh-day Adventists, the 7th Day movement and Seventh Day Baptists) remember the Biblical creation of the heavens and the earth in six days and the Exodus of the Hebrews, and look forward to a future Messianic Age. Shabbat observance entails refraining from work activities, often with great rigor, and engaging in restful activities to honor the day. Judaism's traditional position is that unbroken seventh-day Shabbat originated among the Jewish people, as their first and most sacred institution, though some suggest other origins. Variations upon Shabbat are widespread in Judaism and, with adaptations, throughout the Abrahamic and many other religions.
Hebrew calendar The Hebrew or Jewish calendar (הַלּוּחַ הָעִבְרִי‬, Ha-Luah ha-Ivri) is a lunisolar calendar used today predominantly for Jewish religious observances. It determines the dates for Jewish holidays and the appropriate public reading of Torah portions, yahrzeits (dates to commemorate the death of a relative), and daily Psalm readings, among many ceremonial uses. In Israel, it is used for religious purposes, provides a time frame for agriculture and is an official calendar for civil purposes, although the latter usage has been steadily declining in favor of the Gregorian calendar.
