Days Until Summer Solstice (Northern Hemisphere, approx.)

About Summer Solstice (Northern Hemisphere, approx.)

The Northern Hemisphere's summer solstice — the day with the longest period of daylight in the year — occurs around June 20-22 depending on the specific year, caused by Earth's axial tilt bringing the Northern Hemisphere to its maximum tilt toward the Sun.

The exact date and time shift slightly year to year because a calendar year isn't an exact whole number of Earth orbits (see the site's blog post on why a year isn't always 365 days); this page uses June 21 as a common reference approximation rather than claiming a single fixed date.

Ancient monuments including Stonehenge in England were deliberately aligned to track the solstices, evidence that precise solstice observation predates the Gregorian calendar itself by thousands of years.

Some Nordic countries hold major cultural Midsummer festivals timed around the solstice, including Sweden's Midsommar celebrations, which rank among the most significant traditional holidays on the Swedish calendar.
