Dose anybody know how dose a leap yr affect the birth records???? If at all.....

I'm looking for a birth date for John Butler Cooper 29 Feb 1863 or John B ____?? born to that date Melbourne Vic Au ..... or Eng of that exact date

1863 is a leap yr thought that may affect the records in sum way as it wouldn't let me enter that date into my Ancestry Tree

Hi

How can 1863 be a leap year - I thought they had to be divisible by 4 and therefore must be an even number? 1863 is an odd number.

we have a member of our tree born 29 feb 1924.

And just for interest - today is the 52nd birthday on the composer Rossini

Rules for Calculating Leap Years in the Gregorian Calendar.

1. Every year divisible by 4 is a leap year. (For example, 1996 was a leap year.)
2. Except that years divisible by 100 years are not leap years. (For example, 1900 was not a leap year.)
3. Except that years divisible by 400 years are leap years. (So 2000 was a leap year after all.)

Actually, 1700 would be the last century leap year before 2000 in England, since the Julian Calendar was in effect until Sept 1752, when it got replaced by the Gregorian Calendar.

Hi Malcom

so if there is no more leap yrs until 2000 according to the calendars dose that mean there is was a 29th every Feb & we don't use it??

No, there is NOT a Feb 29th every year!!! Just look at your calendar for last year........or next!

Leap years occur every 4th year, where the year number is divisible by 4

BUT...where the year is a 'Century' year, the year number must be divisible by 400 for it to be a Leap year.

THIS YEAR IS A LEAP YEAR...........the next one is 2012

A year is really 365 + a quarter days long - those quarter days are added together to make an extra day on 29th Feb once every 4 years. I believe that the quarter day will not be precisely 6 hours long, so in the centuary years we have to catch up again by losing that extra day.
