When is the summer solstice?

This year, the summer solstice is on Thursday, June 20, which marks the first astronomical day of summer for the Northern Hemisphere. It also means it is the day with the longest daylight hours of the year, and subsequent daylight hours will grow shorter and shorter until the winter solstice on Dec. 21.

Things are opposite in the Southern Hemisphere: June 20 will mark the start of the winter season, with their summer solstice on Dec. 21.
