Rosh Hashanah literally means "head of the year" and is celebrated on the first day of the month of Tishri on the Jewish Calendar.
Hence, this is the day that begins the Jewish New Year.
It is also known as Yom Teruah, the day of the sounding of the shofar, the "Blowing of Trumpets", and "The Feast of Trumpets".
Rosh Hashanah is also one of the 7 major annual "Feast days" of the Jewish Year.
The commandment to observe Rosh Hashanah is found in Leviticus 23:23-25:
"And the Lord spake unto Moses, saying, 'Speak unto the children of Israel, saying, In the seventh month, in the first day of the month, shall ye have a sabbath, a memorial of blowing of trumpets, an holy convocation. Ye shall do no servile work therein: but ye shall offer an offering made by fire unto the LORD.'"
This year, 2011, Rosh Hashanah begins at sundown on Sept 28th and ends at sundown on the 30th
