1. The Jewish New Year

Rosh Hashanah is the Jewish New Year and according to Jewish tradition marks the anniversary of the creation of the world. The phrase Rosh Hashanah literally translates to "Head of the Year." Rosh Hashanah occurs on the first and second days of the Hebrew month of Tishrei (which usually falls sometime in September or October on the secular calendar). As the Jewish New Year, Rosh Hashanah is a celebratory holiday but there are also deeper spiritual meanings tied to the holiday.

2. Judgment Day

Jewish tradition teaches that Rosh Hashanah is also the Day of Judgment. On Rosh Hashanah, God is said to inscribe the fate of every person for the upcoming year in the Book of Life or the Book of Death. The verdict is not final until Yom Kippur. Rosh Hashanah marks the beginning of the Ten Days of Awe, during which Jews reflect upon their actions over the past year and seek forgiveness for their transgressions in hopes of influencing God's final judgment.

3. Teshuvah (Repentance) and Forgiveness

The Hebrew word for "sin" is "chet," which is derived from an old archery term used when an archer "misses the mark." This informs the Jewish view of sin: all people are essentially good and sin is a product of our errors, or missing the mark, as we are all imperfect. A critical part of Rosh Hashanah is making amends for these sins and seeking forgiveness.

Teshuvah (literally "returning") is the process by which Jews atone on Rosh Hashanah and throughout the Ten Days of Awe. Jews are required to seek forgiveness from people that they may have wronged over the past year before seeking forgiveness from God. Teshuvah is a multi-step process for demonstrating true repentance. First one must recognize that they have made a mistake and genuinely desire to change for the better. They must then seek to make amends for their actions in a sincere and meaningful way, and finally demonstrate they have learned from their mistakes by not repeating them. When a Jew is sincere in his or her efforts at teshuvah, it is the responsibility of other Jews to offer forgiveness during the Ten Days of Awe.

4. Mitzvah of the Shofar

The essential mitzvah (commandment) of Rosh Hashanah is to hear the sounding of the shofar. The shofar is generally made from a hollowed out ram's horn that is then blown like a trumpet on Rosh Hashanah and Yom Kippur (except when the holiday falls on a Shabbat, in which case the shofar is not sounded). There are several different shofar calls used on Rosh Hashanah. The tekiah is one long blast. The teruah is nine short blasts. The shevarim is three blasts. And the tekiah gedolah is a single long blast, much longer than the plain tekiah.

5. Apples and Honey

There are many Rosh Hashanah food customs but the most common is the dipping of apples into honey, which is meant to signify our wishes for a sweet new year. Learn more about this tradition in the article: Apple and Honey on Rosh HaShanah.

6. Festive Meal (Seudat Yom Tov)

A festive meal shared with family and friends to celebrate the New Year is central to the Rosh Hashanah holiday. A special round loaf of challah, which symbolizes the cycle of time, is generally served and dipped in honey with a special prayer for a sweet new year. In terms of other kinds of foods that are served on Rosh HaShanah, local customs and traditions vary widely, both between different Jewish communities and from family to family. You can learn about some of the customs in this article: Rosh Hashanah Food Customs.

7. "L'Shana Tovah"

The traditional Rosh Hashanah greeting appropriate for Jewish friends on Rosh Hashanah is "L'Shana Tovah" or simply "Shana Tovah" which loosely translates as "Happy New Year." Literally you are wishing them a good year (see item 2 above). For a longer greeting you can use "L'Shana Tovah u'Metukah," wishing someone a "good and sweet year."

8. Tashlich

On Rosh Hashanah, many Jews may follow a custom called tashlich ("casting off") in which they walk to a naturally flowing body of water such as a river or stream, recite several prayers, reflect upon their sins over the past year and symbolically cast them off by throwing their sins into the water (usually by throwing pieces of bread into the stream). Originally taschlich developed as an individual custom, though many synagogues now organize a special tashlich service for their congregants to perform the ceremony together.

How to Say Happy New Year in Hebrew

How do you say "Happy New Year" to your Jewish friends during Rosh HaShanah, the Jewish New Year? The answer is simple: "L'Shana Tova" which literally means "For a Good Year."   Rosh Hashanah is the Jewish New Year and is a major holiday on the Jewish calendar. In addition to "L'Shana Tova," there are several other things you can say to someone celebrating Rosh HaShanah. For instance, you could simply say "Happy New Year" or "Happy Holiday." In Hebrew, "Happy Holiday" is "Chag Sameach" and in Yiddish it is "Gut Yontiff."
