Nowruz and The Spring Equinox
The first day on the Iranian calendar falls on the March equinox, the first day of spring. At the time of the equinox, the sun is observed to be directly over the equator, and the north and south poles of the Earth lie along the solar terminator; sunlight is evenly divided between the north and south hemispheres.
In ca. 11 century CE major reforms of Iranian calendars took place and whose principal purpose was to fix the beginning of the calendar year, i.e. Nowrūz, at the vernal equinox. Accordingly, the definition of Nowruz given by the Iranian scientist Ṭūsī was the following: "the first day of the official new year was always the day on which the sun entered Aries before noon".

Famous quotes containing the word spring:
“Power corrupts the few, while weakness corrupts the many.... The resentment of the weak does not spring from any injustice done to them but from the sense of their inadequacy and impotence. They hate not wickedness but weakness. When it is in their power to do so, the weak destroy weakness wherever they see it.”
—Eric Hoffer (1902–1983)
