When and What Is the Summer Solstice?
The summer solstice is the longest day of the year. Solstices are opposite on either side of the equator, so the summer solstice in the Northern Hemisphere is the winter solstice in the Southern Hemisphere, and vice versa.

'Solstice' (Latin: 'solstitium') means 'sun-stopping', because the point where the sun appears to rise and set, stops and reverses direction after this day
The first day of spring, summer, fall and winter can either be defined using astronomical events like solstices and equinoxes, or they can be determined based on meteorological factors, such as average temperatures.
Over the centuries, the June solstice has inspired countless festivals, midsummer celebrations and religious holidays.
One of the world's oldest evidence of the summer solstice's importance in culture is Stonehenge in England, a megalithic structure which clearly marks the moment of the June solstice.
