September 13th - 15th is Rosh Hashanah ( רֹאשׁ הַשָּׁנָה‎ )

Rosh Hashanah (Hebrew: רֹאשׁ הַשָּׁנָה‎, literally "head of the year") is the Jewish New Year. The Biblical name for this holiday is Yom Teruah (Hebrew: יוֹם תְּרוּעָה‎, literally "day [of] shouting/raising a noise") or the Feast of Trumpets. It is the first of the High Holy Days or יָמִים נוֹרָאִים Yamim Nora'im ("Days of Awe") which usually occur in the early autumn of the Northern Hemisphere. Rosh Hashanah is a two-day celebration, which begins on the first day of Tishrei. Tishrei is the first month of the Jewish civil year, but the seventh month of the ecclesiastical year.

The origins of the Hebrew New Year are connected to the beginning of the economic year in the agricultural society of the Land of Israel. The New Year was the beginning of the cycle of sowing, growth, and harvest, the latter marked by its own set of major agricultural festivals. The Semites in general set the beginning of the new year in autumn, while other civilizations of Antiquity chose spring for that purpose, in both cases the primary reason being agricultural - the time of sowing the seed and of bringing in the harvest.

The day is said to be the anniversary of the creation of Adam and Eve, the first man and woman, and their first actions toward the realization of humanity's role in God's world. Rosh Hashanah customs include sounding the shofar (a hollowed-out ram's horn) and eating symbolic foods such as apples dipped in honey to evoke a "sweet new year".
