The Faces of Spring

This started out to be a post on Spring and the different faces it presents.  I was about to state that Spring arrives every year on March 20, but decided I should check my facts.  What I found out was that March 20 has not always the definitive beginning of Spring.  Traditionally March 21 was hailed as the first day of Spring, but in recent years that became the exception rather than the rule. 

The vernal equinox landed on March 21, only 36 out of 100 years. And from 1981 to 2102, Americans will celebrate the first day of spring no later than March 20.

In the years 2008 and 2012, those living in Alaska, Hawaii and the Pacific, Mountain and Central time zones will see spring begin even earlier: on March 19. And in 2016, it will start on March 19 for the entire United States.*

Crocus, one of Spring's pretty faces.

Simplified, some reasons for this include the fact that a year is not made up of an even number of days, nor are the seasons.  Also contributing is the fact that the earth's elliptical orbit is changing relative to the sun.

Spring's face can also be fierce.

Another interesting seasonal fact is that Spring and Summer total more days combined than Fall and Winter, but actually Summer and Fall are gaining ground each year.  Spring is losing one minute and Winter is losing one-half minute per year, respectively.  Summer is gaining the minute lost from Spring and Fall is gaining Winter's half minute.

In many parts of the world, Spring's faces are in evidence before the calendar date, and in addition to the pretty flowers and trees and milder temperatures, she is also unpredictable, unleashing drenching rains and violent storms. So go forth and experience all the faces of Spring.
