Calculated with Astronomy Engine, an open-source library verified against the US Naval Observatory and NASA JPL. How we calculate

Northern Hemisphere

first day of astronomical winter, shortest day of the year

Southern Hemisphere

first day of astronomical summer, longest day of the year

At the December solstice the Sun reaches its southernmost point, directly overhead at the Tropic of Capricorn. North of the Arctic Circle it does not rise; south of the Antarctic Circle it does not set.

The exact moment

Solstices and equinoxes are instants, not whole days: the moment is the same everywhere, only the clock time differs by time zone.

The reason is the equation of time, and it is easy to see in real numbers.
