About First Day of Summer
The first day of summer in the Northern Hemisphere coincides with the summer solstice, typically falling on June 20 or 21 each year. It marks the longest day of the year, when the sun reaches its highest point in the sky and daylight hours peak. Many cultures have celebrated the solstice for millennia — from Stonehenge gatherings in England to the Midsummer festival in Scandinavia. For the Southern Hemisphere, June 21 is the winter solstice. This page uses June 21 as the representative date.
