The summer solstice is also named the June solstice, the first day of summer and the day with the most daylight for those of us living north of the equator. At this point in the year, the sun is directly over the Tropic of Cancer and is at its furthest point from the equator. This date is also known as the winter solstice in the southern hemisphere. After today at 7:08 PM EDT, the days slowly start getting shorter.
