Around the 21st of June every year is the June solstice. We might know that it’s the longest or shortest day of the year – depending on which hemisphere you’re in, but why does that happen? And we know of the Tropic of Cancer and the Tropic of Capricorn, but how does the solstice define them? Same with the Arctic and Antarctic circles. Does it fall on the same date each year? Well almost, but it does take some clever human manipulation of the calendar to keep it that way.
