Solstice

A solstice is an astronomical event that occurs twice a year when the Sun reaches its highest or lowest point in the sky at noon, marking the longest and shortest days of the year. The summer solstice, around June 21, has the longest day and shortest night, while the winter solstice, around December 21, has the shortest day and longest night. These events signal the changing seasons, with the solstices being important for various cultures and traditions throughout history, often celebrated with festivals and rituals that honor the changing relationship between the Earth and the Sun.
