It’s a season with two names, fall and autumn. Fall has been in use for 500 years or more, when people described autumn as the time when the leaves fell. It stuck. Merriam Webster online says the roots of autumn are only a littler older and come from the Middle English “autumpne,” from Latin “autumnus.” Its first known use was in the 14th century.
Daylight savings time: spring forward, fall back, right? This year the official date to turn back clocks in most of Canada is 2 a.m. Nov. 3. First suggested by Benjamin Franklin in 1784, daylight savings has as much to do with saving electric heat and light as anything else. So not surprisingly, most countries waited until electricity came in to jump on DST. That means the widespread use of DST didn’t happen until after the First World War.
As an energy saving measure, U.S. President George Bush extended daylight saving time by four weeks in 2007.
Autumn equinox, like spring equinox, is the celestial phenomenon that happens when the sun is directly in line with the Earth’s equator. The date varies from year to year because the earth travels around the sun in a slight wonky orbit.
When the equinox occurs, it means day and night are roughly equal, 12 hours of daylight, 12 hours of darkness. But some experts still debate the timing and insist day and night are divided equally four days after the equinox passes.
Some experts say northern lights are really better in the fall than in the winter, because the geomagnetic storms that trigger the aurora borealis are twice as frequent in the fall.
Fall gets its own full moon, the Harvest Moon, the full moon closest to the fall equinox. It was traditionally called the harvest moon after the habit of farmers who use it to harvest their crops.
The reason it looks so big this time of year has to do with the full moon’s path around the Earth. At fall equinox, the angle of the moon changes on the horizon and it rises earlier in the evening, usually by 20 minutes or so. The effect is called the moon illusion. Dust and clouds close to the horizon give the moon it’s Halloween glow.
Best of all: Mild days and cool nights mean NO BUGS.
