The bad news for those who like daylight is we won't have much on Friday.
Dec. 21, 2012 — aside from being the supposed end of the world — is the winter solstice in Earth's Northern Hemisphere, according to The Old Farmer's Almanac. The sun will rise at 7:24 a.m. and set at 4:53 p.m.
The good news is days begin getting longer again on Saturday.
The sun's path will reach its southern-most high noon position in the sky, directly over the Tropic of Capricorn, according to An Almanac Minute: The Winter Solstice.
Friday also is the official first day of winter.
