Definition: Passover
Passover begins on the 15th and ends on the 21st or 22nd day of the month of Nisan (March or April)..

Passover (also known as Pesach and the Festival of Unleavened Bread) is a spring holiday commemorating the Exodus, one the most important events in the history of Judaism and an important foundation for all Jewish beliefs. Passover remembers the liberation of the Hebrews from slavery in Egypt in the time of Moses (circa 13th century BCE). Many of its observances are instituted in chapters 12 to 15 of the book of Exodus.

Passover's name comes from the last of the Ten Plagues visited on the Egyptians by Yahweh before the Exodus. All firstborn male children were killed, but those Hebrew households that had slaughtered a lamb and marked their doorposts with its blood were "passed over." It is also an agricultural holiday commemorating the beginning of the harvest season, but this aspect of Passover is not emphasized.

Passover Dates

Passover begins on the 15th day of the month of Nisan and ends on the 22nd (21st in Israel and among Reform Jews). It is a joyful time of family togetherness, but also one of prescribed ritual and strict rules. In addition to the special dietary laws described above, work is prohibited on the first two and last two days of Passover (first and last day in Israel and Reform Judaism). The day before Passover is the Fast of the Firstborn, a minor fast undertaken by all firstborn males.

The degree of work that is forbidden on major holidays like Passover is less strict than on the Sabbath. Leviticus 23:3 commands the Jews to "do no manner of work" on the Sabbath, whereas Leviticus 23:7 requires them to "do no manner of servile work" on the festivals. The general interpretation of the latter commandment is that work can be done on the festivals if it contributes to the enjoyment of the festival and could not have been done beforehand. Thus baking bread or grinding fresh coffee, for example, is allowed on holidays but not on the Sabbath.

Passover Food

To commemorate the suffering of the Hebrews while in Egypt and their departure in haste at the Exodus (no time for the bread to rise), no leaven may be eaten during Passover. Matzah (or matzo) - unleavened bread - is therefore a central feature of the festival. In addition, all leaven (chametz) must also be completely removed from the house during Passover, a symbolic way of removing the "puffiness" (arrogance, pride) from one's soul.

Chametz includes anything made from the five major grains (wheat, rye, barley, oats and spelt) that has not been completely cooked within 18 minutes after coming into contact with water; for Ashkenazic Orthodox Jews, chametz also includes rice, corn, peanuts, and beans (all of which are used to make bread). The morning before Passover, a formal search of the house is undertaken, and any remaining chametz is burned. Because of this observance, Passover is also known as "The Feast of Unleavened Bread."

The Passover Seder

The central observance of Passover is a ritual meal shared by Jewish families on the first and second nights (Jews in Israel and Reform Judaism omit the second night), called the seder (Hebrew for "order"). The seder meal consists of recited benedictions and explanations, ritual handwashing, four cups of wine, and symbolic foods including matzah, bitter herbs, and crushed fruits. Eating, drinking, and other rituals occur at specified intervals. The recitations are set out in the Haggadah, a special book that tells the story of the Exodus for the purpose of the Passover celebration.

Prior to eating the Passover meal, the youngest member of the family asks the following four questions:

The prepared answers, supplied in the Haggadah, are recited in unison by all present, ensuring the spiritual meaning of the ritual is preserved for future generations.

Counting the Omer During Passover

On the second night of Passover, the Counting of the Omer begins. It will last for seven weeks (49 days) until the day before Shavuot. Leviticus 23:15 directs that the days should be counted during this time, which reminds the Jews that the Exodus (which is commemorated on Passover) was not complete until the giving of the Torah (which is celebrated on Shavuot).

Each night during the Counting of the Omer, Jews recite a blessing and state the number of weeks and days of the Omer. The days are spent in semi-mourning, to commemorate a plague in Jewish history. No weddings, parties, or dances are held.

On the 33rd day of the Omer (which occurs on the 18th of Iyar), these mourning practices are temporarily lifted to celebrate a break in the plague. This is a minor holiday called the Lag b'Omer ("33rd of the Omer").
