June 21st. – First Day of Summer
The June solstice occurs on Tuesday, June 21, 2022, at 5:14 A.M. EDT.
This solstice marks the official beginning of summer in the Northern Hemisphere, occurring when Earth arrives at the point in its orbit where the North Pole is at its maximum tilt (about 23.5 degrees) toward the Sun, resulting in the longest day and shortest night of the calendar year. (By longest “day,” we mean the longest period of sunlight hours.) On the day of the June solstice, the Northern Hemisphere receives sunlight at the most direct angle of the year.
