The Persians and Nowruz
While it is still celebrated in Iran and other parts of the Middle East and Asia, the roots of Nowruz (or "New Day") reach far back into antiquity. Often called the "Persian New Year," this 13-day spring festival falls on or around the vernal equinox in March and is believed to have originated in modern day Iran as part of the Zoroastrian religion. Official records of Nowruz did not appear until the 2nd century, but most historians believe its celebration dates back at least as far as the 6th century B.C. and the rule of the Achaemenid Empire. Unlike many other ancient Persian festivals, Nowruz persisted as an important holiday even after Iran's conquest by Alexander the Great in 333 BC and the rise of Islamic rule in the 7th century A.D.
