Why is February 29 called leap day, and what would happen if leap years went away?

It's not every year that you see February 29 on the calendar -- and it's not technically every four years either.. But for others, its all about the science and math behind the number of days it takes Earth to orbit around the sun.

"If we didn’t account for this extra time, the seasons would begin to drift," the article goes on to say."This would be annoying if not devastating, because over a period of about 700 years our summers, which we’ve come to expect in June in the northern hemisphere, would begin to occur in December." "Over time, these extra 44+ minutes would also cause the seasons to drift in our calendar," the article goes on to say."For this reason, not every four years is a leap year."The rule is that if the year is divisible by 100 and not divisible by 400, leap year is skipped, the magazine says.
