Say goodbye to summer with a salute to Monday night’s “harvest moon,” the last full moon before the Northern Hemisphere’s fall equinox on Wednesday, Sept. 22.

When is the harvest moon?

The Americas can hope to see a full moon by Monday evening and evening through Tuesday morning — as Europe, Asia, Australia and the vast majority of Africa enter their evening and evening hours on Sept. 21, which is their second to see it.

That implies the full moon has as of already ascended for the Western-most US time regions, and by precisely 7:55 p.m. for the East Coast, as indicated by NASA.

Moon’s meaning could be a little more obvious.

September’s full moon harmonizes with the traditional reap period of North America and Europe, which lit the way for laborers who worked through dull hours to pull crops. As the sun momentarily squares with the equator on the pre-winter equinox, prior to moving concentration toward the Southern Hemisphere, the time among nightfall and moonrise is abbreviated. That implied old ranchers could keep their workdays going into the night immediately.

What is the autumnal equinox?

The Northern Hemisphere enters fall as the Earth slants to point toward the sun from the opposite side of the equator — set apart by less long stretches of light. Simultaneously, our Southern partner introductions to spring, called the vernal equinox, which means they’ll receive a large portion of the sun’s rewards for the following a half year.

The fall equinox offers way to the colder time of year solstice — on Dec. 21 for the Northern Hemisphere — when the Earth’s pole arrives at its farthest slant away from the sun.

What does Neil Young have to do with the harvest moon?

The Canadian artist musician composed ostensibly one of the best love tunes ever, called “Reap Moon,” for his 1992 record by a similar name. In case you’re in for a decent cry, look at the remarks part of the YouTube video for the tune — a record of incalculable accolades for lost loves by online media users.
