The summer solstice means the precise moment in a year when the Sun reaches its highest position in the sky, and also the day when the time of daylight is the longest. It has been celebrated in most known cultures as a celebration of light and fertility.
The word "solstice" derives from Latin, and means approximately "sun standing still".
In Finland, summer solstice has been known as "mittumaari", but is nowadays celebrated as Juhannus. Summer solstice occurs June 21, 2011, at 17:16, in the Northern Hemisphere.
