As the earth does not circle the sun in exactly 365 days, the equinoxes and solstices do not always come on the same day. The earth takes approximately 365.25 days to go around the sun, and our yearly calendar is 365 days.

Spring comes before summer and after the winter. The first day of spring is called the vernal equinox.

In spring, plants grow faster and bloom as they respond better to spring's temperature and light.

In the Northern Hemisphere, spring runs from March. The March equinox (aka vernal equinox or spring equinox) happens when the sun passes the equator line on its way to the north.

Days in spring are shorter than summer days. As the time passes in the spring daylight time increases and nighttime decreases.

The spring season was originally called Lent in Old English. Starting in the 14th century, that time of the year was called "springing time," a reference to plants springing up from the ground.

The first day of spring is marked by the Spring Equinox, falling on March 19, 20, or 21 every year.

Spring in the Southern Hemisphere runs from September 1st to November 30.

Spring runs from Vernal Equinox to Summer Solstice in the Northern Hemisphere.

While the Northern Hemisphere experiences spring from March to June, it is autumn in the Southern Hemisphere.
