Note: The morning of April 19 in 2019 begins the Fast of the Firstborn, in which observant firstborn sons fast to commemorate the salvation of firstborns in ancient Egypt.

SUNSET FRIDAY, APRIL 19: The intensive search for chametz is over, and tonight, Jews begin the joyous festival of Passover—the most widely observed of all Jewish traditions. After weeks of painstakingly ridding their homes of chametz—any grain product associated with fermentation—Jews join family and friends for a Passover Seder (ritual meal). It’s the 15th day of Nisan in the Jewish calendar, and tonight, the seven- or eight-day festival of Passover begins, commemorating the ancient Israelites’ liberation from slavery in Egypt. (Jews in Israel observe Passover for seven days, and Jews of the Diaspora observe eight.)

Among the events in the biblical story recalled during the Seder, Jews give thanks to G_d for “passing over” the homes of those whose doors were marked with lamb’s blood during the biblical Plague of the Firstborn, for helping them to escape safely from Egypt’s army and for eventually leading them to freedom. The Passover Seder is an extended meal that often lasts several hours, and is filled with ceremonial prayers, rituals, specific foods and drinks and careful table settings. During the Seder, the story of the Exodus is recalled through a recitation of the Haggadah.

Did you know? In Jewish families, young and old get involved in cleaning out the chametz as a way of remembering this key part of the Exodus: As the Israelites left Egypt, they moved so quickly that their bread was not able to rise. To this day, unleavened matzo bread is a common element on Seder tables.

During Passover, the Torah obligation of the Counting of the Omer begins. The omer, a unit of measure, is used to count the days from Passover to Shavuot.

MATZO: THE 18-MINUTE CHALLENGE

Baking matzo is no easy feat: only 18 minutes are allowed between the mixing of flour and water to the finishing of baking. Elaborate measures are taken to ensure the mixture does not rise.

Many Jewish families switch to different dishes, eating utensils and cooking equipment to avoid any contact with traces of foods containing chametz. Chametz is defined as anything involving biological leavening, which includes simply wetting grains and letting them stand for more than 18 minutes. Five grains, in particular, are identified: wheat, barley, spelt, rye and oats.

THE SEDER

The Seder includes many steps and lasts for hours. (Stressing over the pressure of hosting a Seder? Take some advice from a cookbook veteran in this article from the Washington Post. Or, try a Passover app.) All adults present at the Seder are required to drink a total of four cups of wine during the Passover Seder, and further, the Mishnah commands that even the poorest man in Israel has an obligation to drink. Interspersed throughout prayer and stories are the breaking of matzah (unleavened) bread; the washing of the hands; the eating of the symbolic elements on the Seder plate; and, of course, the eating of the holiday meal itself. The whole evening ends with a joint exclamation: “Next year in Jerusalem!”

For the next seven days—or eight, in the Diaspora—Jews will partake of no chametz at any meal. Jews commonly enjoy foods such as potato starch cakes, Gelfite fish, chicken soup with matzah balls and generous amounts of egg.

SEDERS, THE LAST SUPPER—AND A COMMON LINK

Christians teach that Jesus’s final journey to Jerusalem was to observe Passover, forever linking the two sacred seasons. Yet while biblical scholars disagree on whether Jesus’s Last Supper was an actual Seder, “Christianized” Seders are widespread at this time of year—and the practice appears to be growing among evangelicals. Sometimes called “baptized” or “Messianic” seders, the traditional Jewish ritual is changed to turn the meal into a remembrance of Jesus’s Last Supper.

This practice has always been controversial in interfaith settings, though, and Jewish leaders note that the practice distorts their traditions. That’s why the world’s largest Christian church, the Catholic church, forbids its parishes to Christianize the Seder. Instead, Catholic leaders encourage their billion-plus followers to visit authentic Seders—or to invite a rabbi to lead a model Seder to demonstrate the ritual for Christians. Catholic bishops say that “the primary reason why Christians may celebrate the festival of Passover should be to acknowledge common roots in the history of salvation. Any sense of restaging the Last Supper of the Lord Jesus should be avoided.” Many Jewish leaders welcome this approach to sharing their traditional meal.

Invited to a Jewish Passover Seder? The proper greeting is “Happy Passover” or “Happy holiday,” which in Hebrew is “Chag samayach” (hahg sah-MAY-ahk). A Seder plate will be located on most Seder tables, on which are symbols of various aspects of the Passover story. A Haggadah (hah-GAH-dah), a text in Hebrew and English that tells the Passover story and its meaning for each generation, is read during the meal. There are hundreds of different versions of the Haggadah, with many focusing on different elements of the holiday or interpreting it from a particular perspective, such as feminism or ecology.
