kesäpäivänseisaukseseen

Kesäpäivänseisaus, known in English as the summer solstice, marks the longest day and shortest night of the year in the Northern Hemisphere. It typically occurs around June 20th or 21st. On this day, the Northern Hemisphere is tilted most directly towards the sun, resulting in the sun reaching its highest point in the sky at noon.

This astronomical event has been recognized and celebrated across various cultures for millennia. Ancient civilizations often incorporated the summer solstice into their calendars and religious observances, frequently associating it with fertility, abundance, and the peak of summer. Many traditions involve gatherings, bonfires, and rituals designed to honor the sun's power and the bounty of the harvest season.

The exact date of the summer solstice can vary slightly due to the Earth's elliptical orbit and the Gregorian calendar system. It signifies the moment when the sun's declination is at its most northerly point. Following the summer solstice, the days begin to gradually shorten, and the nights lengthen, leading into the autumn season. The summer solstice is a significant astronomical marker, influencing seasonal changes and holding cultural importance in many parts of the world.
