We talked about this at school today and what we got was Julius caesar added a leap year to the calendar when Galileo told him about it. If we didn't have the leap year than seasons would be shifted and winter would be in the summer time. Hope I helped ~LaDessy~
We have leap years because when we go around the sun it doesn't exactly take 365 days a year so we make an extra day each year but still that doesn't exactly equal the whole trip around the sun so every 350 years we may lose a day of the year.
hmm i cant answer this question but i know how we know its a leap year 2012 feb. 29 because u divide it by 4 if it doesnt have a decimal in the number on a calculater if it doesnt then its good nevermind forget about it sorry i'm littler then you sorry :( if your older then 11 yea your oder
I honestly didnt know until I read these answers but its to keep up with the seasons because the earth takes a few hours more than a year to orbit the sun and adding an extra day every four years evens it out.
When a year was originally divided as it is today in the calendar we use today, time-telling was not perfectly accurate. every year is basically 365 days and 6 hours, but since 6 hours aren't a full day the hours add up over 4 years becoming a full 24 hour day. Believe it or not, there are also leap seconds.
We have leap years, so that the calendar can catch up with the planet. The planet orbits around the sun, once a year or 365 days. We need an extra day to catch up with the planet, so we don't get thrown off.
