Longest Day Of The Year 2024 Usa. Fast forward six months, and the shortest day of the year will come on december 21, 2024—the winter solstice. The summer solstice happens when the sun reaches its highest point in the sky and marks the longest day of the year.

The exact day length depends on. During the summer solstice the sun is at its highest point in the sky and travels the longest path, which causes the longest period of daylight and the shortest night of the year.
