The countdown is on until the Spring Equinox. There are two equinoxes every year. One in March and another in September. This is when the sun shines directly on the equator and the length of day and night is nearly equal.
Seasons are opposite on either side of the equator, so the equinox in March is also known as the "Spring Equinox" in the northern hemisphere. However, in the southern hemisphere, it's know as the "autumnal equinox", which occurs in Fall.
March Equinox in New York, New York, U.S.A. is on Thursday, March 20, 2014 at 12:57 PM
