The first day of the summer solstice begins on Friday, June 20, 2008, sparking the longest day of the year.
The official summer solstice begins at 11:59pm EST on Friday. The summer solstice will end when the vernal equinox (fall season) begins on September 22 at 3:44pm EST.
While the summer solstice begins in the Northern Hemisphere, the winter solstice begins in the Southern Hemisphere. Both hemispheres have opposite seasons.
First day of summer is timed with the summer solstice. For most of the United States, summer begins on June 20. In Europe it’s June 21. In Australia it’s six months later, on December 21.
