On Sunday besides being Father's Day, it was the first day of winter in the Southern Hemisphere.
It is said that it is the shortest day of the year. This is because the sun rises late and sets early. It is the day we have least day light. Why does this happen?
"Have you ever heard of a solstice? There are two solstices every year, one in June and one in December. On about June 21, the North Pole is tilted farther toward the Sun than it is at any other time of the year and the South Pole is tilted farther away from the Sun. The June solstice is the beginning of summer in the Northern Hemisphere. The Northern Hemisphere gets more sunlight on the June solstice than on any other day of the year. On the same day, it’s the beginning of winter and the shortest day of the year in the Southern Hemisphere.
On about December 21, the positions of the North and South poles are reversed. The December solstice marks the beginning of summer in the Southern Hemisphere. That’s why Australians can celebrate Christmas sunbathing on the beach! The same day marks the start of winter in the north."
