What date is the winter solstice?

Answer 1

There isn't a spring solstice!

There is a summer solstice, when daylight is longest (i.e. there is the longest interval between sunrise and sunset). In the northern hemisphere this falls on July 21 or 22 (it varies, depending how recently was the last leap year), and in the Southern Hemisphere on December 21 or 22.

The winter solstice, when daylight is shortest, is on December 21 or 22 north of the equator, and July 21 or 22 in the south.

The mid-point between two solstices is called an equinox. The name means that there is the same interval between sunrise and sunset as there is between sunset and the following sunrise. There is one equinox in spring, one in fall (autumn). The dates are March 21 or 22 (spring equinox in the northern hemisphere, fall in the south) and September 21 or 22 (fall equinox in the north, spring in the south).

==============================

The summer solstice in the northern hemisphere falls on or about June 21 (not July 21 or 22).

The winter solstice south on the equator is on June 21 (not July 21 or 22).

Answer 2

December 21
The 2009 Winter Solstice will occur at 9:47 a.m. on Monday, December 21, 2009. That will be the local time on the western coast of the continental United States.

In other parts of the world, however, local times may be different at that same moment. For example, in England at that moment, the local time will be 17:47 in the late afternoon.
