Describe day length and the position of the subsolar point for each of the four seasonal markers.
The December solstice and shortest day in the winter occurs around December 21 each year, when the subsolar point arrives at the Tropic of Capricorn. This seasonal marker is also called the winter solstice in the Northern Hemisphere and the summer solstice in the Southern Hemisphere. After the December solstice, the subsolar point migrates northward. The March equinox (also called the spring equinox or vernal equinox in the Northern Hemisphere and the fall equinox or autumnal equinox in the Southern Hemisphere) occurs when the subsolar point crosses the equator on or around March 20. Around June 21, the subsolar point arrives at the Tropic of Cancer, marking the June solstice (or summer solstice in the Northern Hemisphere) is the longest day. From there the subsolar point migrates back south. Three months later, around September 22, the subsolar point crosses the equator again, marking the September equinox (or fall equinox in the Northern Hemisphere).
