While many of us across the country got hit with a big dose of Spring fever back in February with unusually mild and above average temperatures all across the country, we can finally say “Welcome Spring” officially early this week. We are talking about the Vernal Equinox.
What is the Vernal Equinox?
The Vernal Equinox is a day in March when the sun is directly over the equator and of equidistance from the moon and sun. For this time of year, this only occurs in the Northern Hemisphere as on the contrary, the southern hemisphere will have their autumnal equinox.
When is it?
Meteorological Spring began on March 1st; however, the vernal equinox doesn’t technically occur until around March 20th. The actual time this occurs changes every year. Why? Well, because our rotation around the earth in a single calendar year isn’t exactly 365 days. Its close to 365 days but not exactly. This means that the equinox technically can occur any time between the 19th and 21st.
This year it is estimated to occur at 6:29am EDT on March 20th, 2017.
Happy Spring, everyone! Well, by tomorrow.
