>>10070631In Judaism the sabbath (Hebrew, “rest”) was a day of the week God set aside for the Jews to rest and worship. The weekly sabbath was one of three kinds of holy days on the Jewish calendar. The other two were the monthly new moons and the seven yearly festivals (Neh. 10:33, Lev. 23, Num. 29:6). Because of the Jewish way of reckoning time, according to which the new day began at sunset rather than midnight, the sabbath actually began at sundown on Friday and lasted until sundown on Saturday (though some Adventists do not realize this and celebrate Saturday from midnight to midnight, according to the modern way of reckoning days).
