Well, we have to say GOOD BYE to the SUMMER!! Where did OUR LOVE GO?? Now it’s time to start pulling out them LIGHT JACKETS…unless you live where I live and it’s STILL HOT AS F! But ANYWAYS, as of 9:54 pm EST it will be Fall Equinox signaling the 1st day of AUTUMN! What just is FALL EQUINOX!??
The term equinox comes from the Latin word equinoxium, meaning “equality between day and night.”
On Saturday, September 22, both the Northern and Southern hemispheres will experience an equal amount of daylight. For those of us in the Northern Hemisphere, it marks the beginning of fall, with daylight hours continuing to shorten until the winter solstice in December. For those south of the equator, it’s the beginning of spring.
Folks right along the equator have roughly 12-hour days and 12-hour nights all year long, so they won’t really notice a thing on September 22.
People close to the poles, in destinations such as Alaska, go through wild swings in the day/night ratio each year. They have long, dark winters and summers where night barely intrudes.
But during the equinox, everyone from pole to pole gets to enjoy a 12/12 split of day and night. Well, there’s just one rub — it isn’t as perfectly “equal” as you may have thought.
The Earth rotates along an imaginary line that runs from North Pole to South Pole. It’s called the axis, and this rotation is what gives us day and night.
However, the axis tilts at 23.5 degrees, as NASA explains. That positions one hemisphere of the planet to get more sunlight than the other for half of the year’s orbit around the sun. This discrepancy in sunlight is what triggers the seasons.
The effect is at its maximum in late June and late December. Those are the solstices, and they have the most extreme differences between day and night, especially near the poles. (That’s why it stays light for so long each day during the summer in places such as Scandinavia.)
Since the summer solstice in June, days have been progressively becoming shorter in the Northern Hemisphere and the nights longer for the past three months.
Welcome to fall equinox!
