First Day Of Spring Today
Today is the first day of spring, or the vernal equinox, which means the sun is aligned over the earth’s equator giving us equal amounts of the sun above and below the horizon.
After today the amount of daylight in the northern hemisphere will increase more than darkness each day until the first day of summer, when the earth will start to tilt back, and the sun appears to track its way back south in our view of the sky.
While it’s the first day of Spring in the northern hemisphere, it’s the first day of Fall in the southern hemisphere.
During early spring, the axis of the Earth is increasing its tilt relative to the Sun, and the length of daylight increases causing the hemisphere to warm significantly causing new plant growth to “spring forth,” giving the season its name.
