I doubt that in the year 2100, 88 years from now, you probably won't be around to worry about it. :-)

That is great information!
However, since the 29th IS my Birthday, I think I will still celebrate
it then:-)
Also, remember that it is not every 4 years! If the year is divisible by
100 then there is no Leap Day, unless it is also divisible by 400. So in
the year 2000 we had a Leap Day but in the year 2100 we will not, so no
birthday for me that year:-(
