Winter Solstice

The December solstice will occur at 05:30 (or 5:30am) Coordinated Universal Time (UTC) on December 22, 2011. It is also known as the winter solstice in the northern hemisphere and the summer solstice in the southern hemisphere due to the seasonal differences.  For those of us in the northern hemisphere, the December solstice marks the day of the year with the least hours of daylight.
