Today is the longest night of the year coming down to the earth's chest. Every year on December 21, the sun crosses the equator and reaches the equator. As a result, the northern hemisphere is the longest night on Earth and December 22 is the shortest day. This orbit of the sun is called the southern equinox.
However, the opposite will be the case in the southern hemisphere at this time. There will be the longest day and the shortest night at the same time.
