TODAY, MARCH 20 is the first day of spring 2010, which is marked by the occurrence of the Vernal equinox 2010. Vernal Equinox represents the first day of spring in northern hemisphere and fall in the southern hemisphere. On a day of the equinox, the centre of the Sun spends a roughly equal amount of time above and below the horizon at every location on the Earth, night and day being of roughly the same length.
The first day of spring equinox 2010 is much awaited after the long and cold winter season. According to astronomy, spring equinox marks the moment when the center of the sun's disk appears directly overhead at the Equator. The name "equinox" is derived from the Latin aequus (equal) and nox (night), because around the equinox, the night and day are approximately equally long. The first day of spring also marks the beginning of Nowruz, the Persian New Year.
This year, the vernal equinox will occur at 17:32 coordinated universal time (1:32 PM Eastern Daylight Time) March 20, 2010.
