Chabad is a worldwide Jewish educational organization that welcomes everybody to learn more about Judaism. The San Mateo group offers prayer services, Bar and Bat Mitzvahs, day camp, Hebrew school for kids and adults and a Sunday school for special-needs students, among other programs. Most programs, including prayer services, are held at Chabad's campus in the Bayshore Corporate Center on South Amphlett just north of Concar Drive. The website has lots of videos and other information, including how to observe Shabbat and the proper candle-lighting times for every Friday of the year.
