The longest day of the year will stretch over two days this year.

The summer solstice – the day on which the sun reaches its highest point in the sky and provides the year's longest daylight – is set to occur late Thursday night across much of the western U.S., followed by an early Friday arrival on the East Coast.

(To be exact, the summer solstice is set to occur at 10:04 PM Pacific Time and 11:04 PM Mountain Time on Thursday, and 12:04 AM Central Time and 1:04 AM Eastern Time on Friday.)
