Jews of all movements celebrate many special days throughout the year and throughout each person's life. Major Jewish holidays include Passover, Rosh Hashanah and Yom Kippur. Hanukkah, historically a minor holiday, has become more prominent in the last century for Jews who live in areas that celebrate Christmas. The Sabbath, a day of rest and worship at the synagogue, is observed each Saturday. In Judaism, all days begin at sunset, so all holidays begin at sundown and end at sundown.

To recognize the role of God and the Jewish community in each person's life, numerous life cycle events are observed with traditional rituals. At the first Sabbath after the birth of a child, the proud father is called forward in the synagogue to recite blessings for mother and child. Eight days after birth, baby boys are circumcised.

At the age of 13, a boy becomes a Bar Mitzvah, or "Son of the Commandment"; at age 12 a girl becomes a Bat Mitzvah, "Daughter of the Commandment." The occasion is marked by the youth's first public reading of the Torah in the synagogue (only boys may do this in Orthodox congregations), followed by a large and joyous celebration.

Jewish wedding ceremonies incorporate many ancient traditions and symbolic gestures (including the well-known breaking of glass), and divorces are obtained within the Jewish community. At death, a Jewish person's body is cared for by the chevra kiddisha, the "holy society," who wash the body and prepare it for burial. The deceased is treated with great respect and never left alone. After burial, the deceased's loved ones enter a formal period of mourning, which decreased gradually over the course of a year. The dead is then remembered and honored each year on the anniversary of death.

In addition to these special days and ceremonies, the Jewish life is marked by regular religious observance. Each Saturday, Sabbath is observed by ceasing work and spending the day in worship at the synagogue and at home with family. The study of Torah and other Jewish scriptures is considered very important, and many Jewish children attend Hebrew school so they can study it in its original language. In everyday life, traditional Jews observe the laws of kashrut, eating only foods that God has designated "kosher." Among non-kosher, or prohibited, foods are pork, any meat that has not been ritually slaughtered, shellfish, and any meal that combines dairy with meat.
