Tonight at 11:24 PM in the Northern Hemisphere the Summer Solstice shall begin. The Summer Solstice marks the time of the longest day (greatest amount of sunlight) of the year. The Sun appears to stand still in the sky, rising at the same exact spot for a few days before beginning it's movement across the horizon again. From this time onward the amount of daylight will decrease until we reach the Winter Solstice in December.
Today is the official start of the Summer season with tomorrow being the first full day of Summer.
An older name for the Summer Solstice is Midsummer. It is under this older name that Wiccans and modern Neo-Pagans celebrate. They also use the word Litha for this day as well. Christians celebrate the Summer Solstice under the guise of St. John's Eve and Day, which is held on June 23-24th.
Wishing All Of My Readers A Wonderful Summer Season!
