Vernal Equinox


Twice a year, around March 20 or 21 and September 22 or 23, the sun shines directly on the equator and the length of day and night are nearly equal in all parts of the world. These two days are known as the March(vernal or spring in the northern hemisphere) equinox and the September equinox. This year, the event happened on March 2o th in the morning. So welcome to Spring, 2010.
