Rosh Hashanah (Hebrew: ראש השנה‎), (literally "head of the year"), is the Jewish New Year. It is the first of the High Holy Days or Yamim Nora'im ("Days of Awe") which occur in the autumn. Rosh Hashanah is celebrated on the first two days of Tishrei. It is described in the Torah as יום תרועה (Yom Teru'ah, a day of sounding [the Shofar]).^[1] Rosh Hashanah customs include sounding the shofar and eating symbolic foods such as apples dipped in honey.

The term "Rosh Hashanah" does not appear in the Torah. Leviticus 23:24 refers to the festival of the first day of the seventh month as "Zikhron Teru'ah" ("a memorial with the blowing of horns"), it is also referred to in the same part of Leviticus as 'שַׁבַּת שַׁבָּתוֹן' or penultimate Sabbath or meditative rest day, and a "holy day to God". These same words are commonly used in the Psalms to refer to the anointed days. Numbers 29:1 calls the festival Yom Teru'ah, ("Day [of] blowing [the horn]") and symbolizes a number of subjects, such as the Binding of Isaac and the animal sacrifices that were to be performed.^[2][3] (In Ezekiel 40:1 there is a general reference to the time of Yom Kippur as the "beginning of the year",^[2]

Constitution Day (or Citizenship Day) is an American federal observance that recognizes the adoption of the United States Constitution and those who have become U.S. citizens. It is observed on September 17, the day the U.S. Constitutional Convention signed the Constitution in 1787.^[2]

The law establishing the holiday was created in 2004 with the passage of an amendment by Senator Robert Byrd to the Omnibus spending bill of 2004.^[3] Before this law was enacted, the holiday was known as "Citizenship Day". In addition to renaming the holiday "Constitution Day and Citizenship Day," the act mandates that all publicly funded educational institutions provide educational programming on the history of the American Constitution on that day.^[4] In May 2005, the United States Department of Education announced the enactment of this law and that it would apply to any school receiving federal funds of any kind.^[5] This holiday is not observed by granting time off work for federal employees.
