This also means the first day of winter has arrived, but if you're not a winter lover, then the countdown to spring has also begun. Eastern Time on December 21. Likely older than Stonehenge, the opening of this enclosed, mound-like structure is designed so that as the sun dawns on the morning of the winter solstice, light shoots down a tiny, cramped passage at a ideal angle to light an interior chamber. While it's winter for those of us in the Northern Hemisphere, people in the Southern Hemisphere experience it as their summer solstice with the longest stretch of daylight.

The number of hours of sunlight you'll get depends on how far from the equator you are. Tampa will see 10 hours, 22 minutes and 17 seconds of daylight Thursday, which is two seconds shorter than Wednesday. Boston's sunlight period ends a bit earlier, at 4:15 p.m., with nine hours and four minutes of daylight.Читайте также: FBI Arrests Man For Alleged Pier 39 Christmas Day Terror Plot
If you live in the southernmost USA, your earliest sunsets are in late November, according to EarthSky.org. And if you happen to live north of the Arctic Circle, you'll get none. However, it's never the day of the latest sunrise or earliest sunset. This is because the earth is traveling its orbit around the sun on a tilted axis. It's an old proverb that certainly has some scientific truth.
"The winter solstice occurs at the moment the Earth's tilt away from the sun is at a maximum", Stephen Schneider told CBS News.
This delay in the arrival of our coldest temperatures is better known as seasonal lag.При любом использовании материалов сайта и дочерних проектов, гиперссылка на обязательна.
