Shofar—Call to Action

What: A shofar is a horn of a kosher animal with the marrow removed. Blow into a shofar and you get a shofar blast. Blow the right sequence of blasts at the right time of year and you've got a great mitzvah.

When: In the Bible, Rosh Hashanah is called "The Day of the Shofar Blast." That's the mitzvah of the day: to hear the blasts of the shofar. Since Rosh Hashanah is two days long, we need to hear the shofar blown during the daytime hours of both of those days (unless the first day falls on Shabbat, in which case we blow the shofar only on the second day). This year, 2011, we blow the shofar on September 29th and 30th.

Why: Basically, because it's a mitzvah. But the blasts of the shofar are also wake up calls. Rosh Hashanah is the time to shake out of our spiritual slumber, reconnect to our source, and recommit to our divine mission in this world.

Who: All Jewish men, women, and children. All of us need to reconnect.

Where: Venue of preference is your local synagogue. There, the shofar is blown after the Torah Reading. Click here to find a synagogue closest to you. No way you can make it? Contact your local Chabad rabbi. He'll do his best to arrange for a shofar blower to pay you a personal visit.

How: It may look simple, but you've got to play by the rules. Unless you know all the rules, leave it to your rabbi or another professional. Here's the basics:

The shofar blower recites two blessings and then blows a set sequence of three kinds of blasts: 1) Tekiah -- an uninterrupted blast lasting for several seconds. 2) Shevarim -- three medium length blasts. 3) Teruah -- a minimum of nine very short blasts.

Do it right and you end up with thirty such blasts on the shofar. That's the minimum requirement. In the synagogue, we blow a total of 100 blasts, with the additional blasts distributed over the course of the prayers that follow the Torah Reading.
