Science behind Leap Year Day


NATIONAL — Whether or not your day has felt out-of-the-ordinary, you won’t see another one like it for four years. That’s because it’s Leap Year Day.

The date comes every four years as a way to compensate for the length of time it actually takes Earth to go around the sun; which is 365-1/4 days.

Astronomers at UI track the Earth’s rotation impacts on our lives. They say, while adding another day to the year for this reason might seem silly, it actually ensures our seasons happen at the right time of the year.

There are also “leap seconds” which help even further correct the calendar. Eventually, we’ll be on time with Earth’s rotations, but that won’t happen for thousands of years.
