As Fall Begins, Here’s When Winter Will Hit the Northern Hemisphere – NBC Chicago

Thursday is a day millions of Americans have been waiting for, as the autumnal equinox finally arrives in the northern hemisphere.

The equinox, which technically arrives at 8:04 p.m. Central Daylight Time, signals the approach of cooler weather and changing leaves, but it also signals the impending winter that many Chicagoans dread. .

So how long do you have to enjoy fall before winter rolls around?

For the Northern Hemisphere, the Winter Solstice, defined as the least sunny day of the year, will arrive on Wednesday, December 21 at 3:48 p.m. Central Standard Time.

While the winter solstice is technically the shortest day of the year in terms of total daylight, with just a shadow below nine hours and 11 minutes of sunshine, it doesn’t actually feature the last sunrise. or the first sunset of the year.

The first sunset of 2022 will actually occur on December 8-9, according to Sunrise-Sunset. On these days, the sun will set at 4:21 p.m. exactly.

From there, sunset will come later in increments of just a few seconds, but the days will technically continue to get shorter until the solstice, as sunrise will occur at increasingly later times.

The last sunset of winter won’t occur until January 5, when the sun rises just before 6:47 a.m. in Chicago. At that time, the days will technically get longer thanks to later sunsets, but they will still continue to start later from a daylight perspective.

A variety of factors go into these dates, primarily involving solar noon (defined as the time when the sun is at its highest point in the sky) not falling exactly at noon, as well as the slowing of the rotation of the Earth around the sun in its annual orbit.
