There was a boy named Billy. His birthday fell in nice and warm summers. Every year he celebrated his birthday on 22nd December. Are you surprised? I sure was..

You see the Earth is a sphere and can be divided into two hemispheres. The line that divides the Earth into the Northern Hemisphere and the Southern Hemisphere is equator .

The Northern Hemisphere includes all of North America, the northern parts of South America, about two-thirds of Africa, all of Asia excluding (parts of Indonesia) and all of Europe.

The Southern Hemisphere includes most of South America, one-third of Africa, all of Antarctica, a small sliver of Asia (parts of Indonesia) and all of Australia/Oceania.

These Hemispheres have very interesting facts about them

• The Northern Hemisphere has almost 90% of the land and the Southern Hemisphere has 90% water. So most of the world population lives in Northern Hemisphere.
• When its is summer in the Northern Hemisphere, its winter-time in Southern Hemisphere.
• Moon seems to be upside down in the Southern Hemisphere.
• Sun rises in East and sets in West in both Hemispheres. Atleast they have something in common :)

Coming back to our question that how Billy celebrated his birthday on Dec 22 in summers? He lived in Australia  :)
