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:
“I care not by what measure you end the war. If you allow one single germ, one single seed of slavery to remain in the soil of America, whatever may be your object, depend upon it, as true as effect follows cause, that germ will spring up, that noxious weed will thrive, and again stifle the growth, wither the leaves, blast the flowers, and poison the fair fruits of freedom. Slavery and freedom cannot exist together.”
—Ernestine L. Rose (1810–1892)
