SUMMER OFFICIALLY BEGINS ON SUNDAY

SUMMER BEGINS AT 12:45 AM CDT


The solstice is an astronomical event that takes place twice a year, when the tilt of the Earth's axis is most inclined toward or away from the Sun, causing the Sun's apparent position in the sky to reach its northernmost or southernmost extreme. The summer solstice marks the longest day of the year and the first day of summer. There are 24 hours of daylight north of the Arctic Circle and 24 hours of darkness south of the Artarctic Circle. We receive more direct rays of sun during the summer.

The earth spins around its axis and the axis is tilted somewhat off the plane of the earth's revolution around the Sun. The tilt of the axis is 23.5 degrees and because of this tilt we get to enjoy four seasons. When the axis tilts towards the Sun, as it does between now and September, it is summer in the northern hemisphere but winter in the southern hemisphere.
