רֹאשׁ הַשָּׁנָה, literally meaning the "beginning of the year" is the Jewish New Year.
The Biblical name for this holiday is Yom Teruah (יוֹם תְּרוּעָה), literally "day of blasting". It is the first of the Jewish High Holidays (יָמִים נוֹרָאִים Yamim Nora'im. "Days of Awe")
Rosh Hashanah is the first two days of the Jewish new year, Tishrei 1 and 2, beginning at sundown on the eve of Tishrei 1.
How do we celebrate? We light candles in the evenings, enjoy festive meals with sweet delicacies during the night and day, prayer services that include the shofar blowing (rams horn) on both mornings, and resting, of course. As on any Jewish holiday, we enjoy meals shared with family and guests.
Symbolic Rosh Hashanah foods include: apples and honey (for a sweet year), pomegranates, fish head, carrots with honey ad sweets.
Shofar: The central observance of Rosh Hashanah is the sounding of the shofar, the ram’s horn, on both days of the holiday (except on Shabbat, which case we blow the shofar only on the second day).
