The winter solstice occurs when the sun is directly over the Tropic of
Capricorn, which takes place this year on Dec. 21 at 12:11 p.m. EST. In
the weeks that follow, the sun's vertical rays will migrate northward
and reach the equator on the first day of astronomical spring. The
south-north migration of the sun in the sky is caused by the tilt of the
Earth's axis and the movement of the Earth around the sun.
