Shabbat service is a Jewish religious service that takes place on the Sabbath, which is a weekly holiday that celebrates creation and offers a respite from the hectic pace of the rest of the week. Shabbat services are held on Friday evening and Saturday morning, and sometimes also on Friday afternoon and on Saturday afternoon and evening. The service is typically led by a shaliach tzibbur, who is the leader of congregational prayers, be it the cantor or another congregant. The service includes prayers, songs, and readings from the Torah. The Shabbat morning service is known as Seder K’riat HaTorah (Service for the Reading of Torah), which includes special prayers and songs that highlight the importance of Torah. The service also includes an expanded version of Pesukei dezimra, a longer version of the Yotzer ohr blessing, the seven-blessing Shabbat version of the Amidah, no Tachanun, a longer Torah reading, and some additional prayers after the Torah reading. The service usually lasts between 2½ and 3 hours, but that can vary based on the congregations pace and the loquaciousness of the rabbi. At the end of the service, people will often greet one another informally as they move into a different space, often a social hall adjacent to the sanctuary, for refreshments and socializing.
