Tomorrow is the first day of Summer. The Summer Solstice will take place in the Northern Hemisphere at 7:57 AM on June 21st (Pacific Daylight Time). The Summer Solstice is also called the estival solstice and occurs in the Northern Hemisphere when the North Pole is at its most extreme tilt towards the sun. The result is the longest day (and shortest night) of the year. The Solstice is also the first day of the season of Summer– although, confusingly, festivals known as Midsummer, take place around the same time, often on June 24.
