Also known as Midsummer.
Midsummer is the period of time centered upon the summer solstice, and more specifically the northern European celebrations that accompany the actual solstice or take place on a day between June 19 and June 25 and the preceding evening. The exact dates vary among different cultures. The celebration predates Christianity, and existed under different names and traditions around the world.
The summer solstice occurs during summer. This is the June solstice in the Northern Hemisphere and the December solstice in the Southern Hemisphere. Since prehistory, the summer solstice has been seen as a significant time of year in many cultures, and has been marked by festivals and rituals. Traditionally, in many temperate regions (especially Europe), the summer solstice is seen as the middle of summer and referred to as “midsummer”. Today, however, in some countries and calendars it is seen as the beginning of summer.
Solstice is derived from the Latin words sol (Sun) and sistere (to stand still).
