The December Solstice.
Here in North America, folks like to call it the "Winter Solstice", but in the Southern Hemisphere, it happens to be the beginning of Summer !
The sun is directly overhead on the Tropic of Capricorn at some time on December 21 or 22.
That moment is technically the beginning of Winter in the northern hemisphere, and the beginning of Summer
in the southern hemisphere.
That is winter solstice in the north, and summer solstice in the south.
