Why is December 21 the Shortest Day of the Year?

Posted by Kyle Brookings on Friday, December 21, 2018

The shortest day of the year in the Northern Hemisphere is the Winter solstice. This year it falls on December 21.

The Winter solstice can be on December 20, 21, 22, or 23.

It occurs when the North Pole is tilted furthest from the Sun.

Since the North Pole is tilted furthest from the Sun it is the day when the Northern Hemisphere receives the least amount of sunlight.

As of tomorrow we will see a bit more daylight each day.

The Sun is directly overhead of the Tropic of Capricorn in the Southern Hemisphere during the December Solstice.

In the Southern Hemisphere, it is the summer solstice and the longest day of the year.
