Full Answer

The shortest day of the year falls on the winter solstice. In the Northern Hemisphere, this is usually between December 20 and December 23. In the Southern Hemisphere, the shortest day is between June 20 and June 22. The December solstice occurs when the North Pole is at its furthest tilt away from the sun.

How much sunlight there is on the shortest day depends on the location and does not necessarily mean the latest sunrise or the earliest sunset. The earliest sunsets usually occur about 2 weeks before the winter solstice and the latest sunrise about 2 weeks afterward. In parts of the Arctic, there is no daylight at all. Variation in the length of sunlight also occurs across the U.S.:

  • Fairbanks, Alaska - 3:42 of sunshine on the shortest day
  • Seattle - 8:25 of daylight
  • Boston - 9:04 of daylight
  • Chicago - 9:08 of daylight
  • New York - 9:15 of daylight
  • Washington D.C. - 9:26 of daylight
  • Miami - 10:32 of daylight

  • Q:

    How do seasons change?

    A:

    The change in seasons is caused by the varying angle of the Earth's tilt from one part of the year to another. A common misconception is that the change in seasons is due to the Earth's slightly elliptical orbit bringing the planet closer to the sun in summer, but, as About.com notes, seasons are different in the northern hemisphere and the southern, which are the same distance from the sun.
