What determines the first day of summer?
The first day of summer is determined by the tilt of the earth’s axis as it rotates around the sun. The day that the North Pole is pointed closest to the sun, the northern hemisphere receives the most light for the longest amount of time.
This day is known as the June or summer solstice, with a solstice being the twice-yearly astronomical occurrence when the sun is the greatest distance from Earth’s equator. (If you’re in the northern hemisphere, that means the sun will sit at its highest point in the sky during the summer solstice; during the winter solstice, it will sit at its lowest.)
As the 24-hour period with the longest “day” and shortest “night” in the 365-day calendar year, the day of the summer solstice marks the first day of the summer season.
If you want to get really technical, the exact time of the summer solstice this year is 11:32 p.m. EST—which means you might want to power up those patio string lights while you ring it in.
Is it the same day every year?
Not exactly, and that is due to how long it technically takes the earth to complete one rotation around the sun. The Gregorian calendar, which is the international standard used for societal and scientific purposes, marks this passage of time—one year—as 365 days. But a solar year is actually closer to 365 days and six hours.
This discrepancy gives us Leap Day every four years, and it also bumps the summer solstice a day or two depending on the year. The first day of summer will always fall on or between June 20 and June 22.
