Last Wednesday was February 29.

This date is very special.

It only comes every four years.

This is because it takes the Earth about 365 days, 5 hours, 48 minutes, and 46 seconds to circle once around the sun.

But our calendar has only 365 days in a year.

So if we didn¡¯t add a day in February every four years, we would lose almost six hours off our calendar every year.

After 100 years, our calendar would be off by about 24 days!
