When Is Summer Solstice 2027?

Summer Solstice 2027 falls on Monday, June 21, 2027 — 295 days from now. Live countdown, dates through 2030, and how the date is set.

The summer solstice or estival solstice occurs when one of Earth's poles has its maximum tilt toward the Sun. It happens twice yearly, once in each hemisphere (Northern and Southern). The summer solstice is the day with the longest period of daylight and shortest night of the year in that hemisphere. At either pole there is continuous daylight at the time of its summer solstice. The opposite event is the winter solstice. The June solstice — the longest day in the Northern Hemisphere — falls on June 20 or 21, set by astronomy rather than the calendar.
