Leap years are necessary because the actual length of a year is 365.242 days, not 365 days, as commonly stated. Basically, leap years occur every 4 years, and years that are evenly divisible by 4 (2004, for example) have 366 days. This extra day is added to the calendar on February 29th.
The 24 hour system isn't perfect. Every day has an extra second or two in accordance with how far along in the leap year section we are in. That eventually adds up and leap year corrects for that by removing those extra days we don't need. If the Gregorian (I think that's name, been almost a decade since school) Calender didn't account for leap years. Eventually both our time keeping and months would be skewed to the point of being very inaccurate.
The year is not exactly 365 days, it is closer to 365.25 days. Every four years, these quarter-days add up to a full day and we change the calendar. The leap year was started by the Gregorian Monks in the middle ages.
Leap year was established because of the rotations of the orbits. This caused the calendar and dates to be a little off each year. So man created leap year to even out the calendar to this orbit change. Without leap year we would be many days and even years off.
The year isn't an exact multiple of the length of the day; there are 365.24 days per year.
There are a number of different calendars in use in the world. If our calendar is to remain synchronized with the length of the year, then we need to make some adjustments every few years to enforce that. Not every calendar remains synchronized to the solar year; the Islamic calendar, for example, does not.
In the Gregorian calendar, the "standard civil calendar" used by most English-speaking people, we add one day to every fourth year to keep things synced up.
it is something to do with how it takes 365 days to do a full orbit . sorry thats all I know
Yes, is this repeating?
3080 will be a leap year.
1776 was a leap year
No. If the year number can be divided by four then it's a leap year. 2012=Leap year.
2112 will be a leap year. If you meant 2012, then it too was a leap year.
Yes 2016 is a leap year.
no,the next leap year is 2012!No, it is not a leap year.
2052 will be a leap year.
The year 3300 will not be a leap year.
The year 2225 is not a leap year.
No, 1564 was not a leap year.
