The Earth Rotates 366.25 Times per Year

Statement: The Earth rotates on its axis 366.25 times per year

That is, when the Earth completes one whole revolution around the Sun (360 degrees), which is a year, it has rotated on its own axis 366.25 times.

This is going to be old news to some people, but I think it will still catch a lot of people out. The obvious thing I am hoping you are wondering here is that you thought there were only 365 days in a year. Some of you will know there are actually 365.25 days in a year, hence the reason for a leap year every 4 years. But where does that extra rotation come from to make it 366.25?

 Have a think before reading the solution below. Hopefully the wonders of jQuery will have hidden it from you until you click.
