Why do we have a leap year?
Our solar year (the time required for Earth to travel once around the Sun)
is 365.24219 days.
Our calendar year is either 365 days in non leap years or
366 days in leap years (Feb 29th inserted).
A leap year every 4 years gives us 365.25 days,
sending our seasons off course and eventually in the wrong months.
To change .25 days to .24219, we need to skip a few leap days (Feb 29ths) ....
century marks not divisible by 400. So with a few calculations tweek the calendar by skipping 3 of 4 century leap years to average out our calendar year to 365.2425, which is pretty darn close to the solar year 365.24219.
Here’s the history:
The Romans originally had a 355-day calendar. To keep up with the seasons, an extra 22 or 23-day month was inserted every second year. For reasons unknown, this extra month was only observed now and then. By Julius Caesar’s time, the seasons no longer occurred at the same calendar periods as history had shown. To correct this, Caesar eliminated the extra month and added one or two extra days to the end of various months (his month included, which was Quintilis, later renamed Julius we know it as July). This extended the calendar to 365 days. Also intended was an extra calendar day every fourth year (following the 28th day of Februarius). However, after Caesar’s death in 44 B.C., the calendars were written with an extra day every 3 years instead of every 4 until corrected in 8 A.D. So again, the calendar drifted away from the seasons. By 1582, Pope Gregory XIII recognized that Easter would eventually become closer and closer to Christmas. The calendar was reformed so that a leap day would occur in any year that is divisible by 4 but not divisible by 100 except when the year is divisible by 400. Thus 1600 and 2000, although century marks,
have a Leap Day.
Ok, I got all these information from the internet! (:
Because I myself doesnt really know what is a leap year for! (:
I also found out that today is
