The First Day Of Spring
The vernal equinox 2009 occurs today, March 20, bringing in the official beginning of spring.
The spring equinox takes place at 7:44 a.m. EDT.
The vernal equinox takes place when the sun passes directly within the duration of the equator, diving night and day to equal lengths. It is one of two equinox happenings within the duration of the year: The autumnal equinox takes place in September and marks the commence of the end season for the northern hemisphere.
The first day of spring is no guarantee of spring-like weather though.
