GLENVIEW, IL — The darkest day of the year is upon us, which means the winter solstice is just days away in Glenview.
The celestial holiday celebrated through the ages as the beginning of light arrives in Glenview on Dec. 21 at 9:59 a.m. CT. If you’re not a fan of daylight, you’re in luck —we’ll see only nine hours, 6 minutes and 23 seconds of sunlight on the first day of winter.
Whether you’re a fan or not, there’s plenty Glenview residents can do to embrace the winter season.

For anyone hoping to stretch their winter solstice revelry into the evening hours — or into the next day, perhaps — here’s a bonus: The Ursid meteor shower is likely to peak the morning of Dec. 22.
The annual Ursid meteor shower, which runs from Dec. 17-26 each year, is a minor meteor shower with only five to 10 shooting stars an hour. Still, a nearly moonless sky translates into excellent viewing conditions in Glenview, depending on the weather.

Accuweather is forecasting partly cloudy skies with a 13 percent chance of precipitation in our area Tuesday night into Wednesday morning.
Ursid meteors radiate most near the star Kochab in the Little Dipper, according to EarthSky.org. The star Polaris — or the North Star — is also part of the Little Dipper. If you can’t find the Little Dipper, use the Big Dipper. No matter what time of year you look, the two outer stars in the Big Dipper’s bowl always point to Polaris, marking the end of the Little Dipper’s handle.
The solstice isn’t something you see but rather something that occurs — though you may want to mark the 2021 solstice by taking a picture of your shadow at noon. Because the sun is at its lowest arc across the horizon, it casts long shadows. Shadows at noontime on the day of the winter solstice will be the longest of the year.
The winter solstice occurs at the exact moment the North Pole tilts the farthest away from the sun. On Sunday, the days begin growing a wee bit longer every day until the summer solstice, after which the days start getting shorter again.
On the winter solstice, the sun seems to stand still directly over the Tropic of Capricorn, which is 23.5 degrees south of the equator. During the summer solstice, which occurs in June, the sun is directly over the Tropic of Cancer.
The winter solstice, the oldest-known winter celebration, is derived from the Latin word “solstitium,” which means “sun standing still.” In ancient times, it was both spiritually and scientifically essential and marked the changing of the seasons. The best place in the world to observe the winter solstice is at the prehistoric monument Stonehenge in Wiltshire, England, believed to have been erected by ancient Celtic druids to line up the exact position of the sunset on the winter solstice.
The winter solstice may explain why Christians celebrate the birth of Jesus in December. The Bible isn’t specific about when Jesus was born. Some people believe Dec. 25 may have been selected by Pope Julius I as the date of Christ’s birth to replace the ancient pagan Roman midwinter festival called “Saturnalia” with a Christian holiday.
The late Harry Yeide, who taught religion at George Washington University for nearly 50 years and died in 2013, once told National Geographic that as the Christmas celebration moved West, “the date that had been used to celebrate the winter solstice became sort of available for conversion to the observance of Christmas.”
For example, several rituals associated with Christmas — dinner feasts, gift-giving, and decorative wreaths — are rooted in pagan winter solstice rituals.
It may surprise you that the earliest sunsets and latest sunrises don’t occur on the winter solstice. It seems counterintuitive, but as Earthsky.org explains it, the key is understanding solar noon, the time of day the sun reaches its highest point in the sky. True solar noon occurs 10 minutes earlier on the clock in early December than it does at the solstice. When true noon occurs later on the solstice, so do the sunrise and sunset times.
“It’s this discrepancy between clock time and sun time that causes the Northern Hemisphere’s earliest sunset and the Southern Hemisphere’s earliest sunrise to precede the December solstice,” Earthsky.org says. “The discrepancy occurs primarily because of the tilt of the Earth’s axis. A secondary but another contributing factor to this discrepancy between clock noon and sun noon comes from the Earth’s elliptical — oblong — orbit around the sun.
“The Earth’s orbit is not a perfect circle, and when we’re closest to the sun, our world moves fastest in orbit. Our closest point to the sun — or perihelion – comes in early January. So we are moving fastest in orbit around now, slightly faster than our average speed of about 30 kilometers (18.5 miles) per second. The discrepancy between sun time and clock time is greater around the December solstice than the June solstice because we’re nearer the sun at this time of year.”
