Rosh Hashanah means Jewish families around the world are getting ready to usher in the Jewish New Year.
Rosh Hashanah translates from Hebrew to mean "start of the year," and the holiday is marked by services in a synagogue, as well as traditional holiday meals with family. One example of this is dipping apples into honey, to mark a "sweet" new year.
If you'd like to wish a Jewish friend a happy new year, the traditional greeting is "shana tova," which literally means "good year." (You can hear a pronunciation of the phrase here.)
Of course, just saying "happy new year" works perfectly fine as well.
