RE: Determine birth date 6s0 format

Nope. Leap centuries have different rules than leap years. Here's the
US standard.

Yes they are...

Every year that's divided by 100 that has no remainder is in fact a leap
year. Why do you think there was a leap year in 2000 for?

There's exactly 25 leap years in a centry...

I'm really not following this whole deal about 100 and 400 years... why
not
just divide by 4 and check the remainder. If 0 then it's a leap year.
Unless I'm not unstanding the rules of leap year.

1900 would have been a leap year as was 2000.

1900/4 = 475.0
2000/4 = 500.0

Years evenly divisible by 100 are not leap years UNLESS they're evenly

Lim, your example is not the best one; if Feb. 29 is valid for

specific

year, it is valid for the (year-100); the opposite is, also, true...
I thing there is only one exception to this rule, the year 1900

(which,

if I'm not mistaken, it wasn't a leap year, but 2000 it was...)

Umm. The opposite could be true also. Fed 29 might not be valid for
2037 but it is for 1937.

Well, have fun!!!.

Date is always tricky. When doing the subtracting 100 logic, you

might

want to convert the date to a ISO 8 digits numeric field first.
Subscriber this 8 digits numeric field by 100 and check the date to

make

sure it is still valid before use it.

Feb 29 might be valid for 2037 and not valid for 1937.

Thanks all;

I had actually "doodled" with the concept of subtracting 100 from the
date, but wasn't sure if this was an accepted way to go.

Thanks for all your help.
