For those who are always fretting about not having enough time in the day, today is your day. While the summer solstice technically happens on Wednesday at 12:24 a.m. ET, it's Tuesday that's getting that blissful extra bit of sunlight.

On the summer solstice — the longest day of the year and the first official day of summer — the sun sits directly overtop the Tropic of Cancer, which rests at 23.5 degrees north latitude. The positioning of the Earth relative to the sun allows the Earth's northern hemisphere to bask in more direct sunlight on the summer solstice than on any other day of the year. The southern hemisphere celebrates the winter solstice — the shortest day of the year — on the day the northern hemisphere celebrates the summer solstice.
