About First Day of Summer
The first day of Summer 2027 (the Summer Solstice) is on Monday, June 21st. This is the longest day of the year in the Northern Hemisphere, with the most hours of daylight. It marks the astronomical start of summer and the beginning of warm-weather activities, outdoor festivals, and vacation season.
History & Significance
The Summer Solstice has been celebrated for thousands of years across cultures worldwide. Ancient civilizations built monuments aligned with the solstice, including Stonehenge in England and Newgrange in Ireland. In Scandinavia, Midsummer remains one of the most important holidays. The solstice occurs when the Earth's axial tilt is most inclined toward the Sun, resulting in the longest period of daylight.
