Who’s Ready for a Change? In Seasons That Is!

19 Mar 2015, 2:15 pm

Spring officially starts Friday, March 20, at 6:45 p.m. ET, though signs of spring have already been popping up around the country.

The vernal, or spring equinox marks when the sun crosses the equator as the Earth’s tilt forces the sun’s angle north towards the Tropic of Cancer (located at 23.5 degrees north). It marks the first day of spring for the Northern Hemisphere and the first day of fall for the Southern Hemisphere.

ARTICLE 1 (1)The word equinox is defined as equal night or when day and night are of approximately equal duration. On the first day of spring (and fall), it’s thought that everyone on Earth experiences 12 hours of daylight and 12 hours of night. This isn’t entirely true though. It all depends on a location’s latitude with most seeing approximately 12 hours of equal day and night.
ARTICLE 2 (1)Regardless, the Northern Hemisphere will enjoy an increase in daylight over the next few months. Come June 21 (the first day of summer), daylight will slowly decrease as Earth tilts again and the angle of the sun makes it’s way back south towards the Equator and eventually down toward the Tropic of Capricorn.
