Leap Years

Why?

Leap years are a pain.  Every so often they come along and dump an extra 
day on the end of February; a month so many people wish to progress out of 
post-haste.  As if February wasn't already unique enough, having only 
twenty-eight days under normal circumstances.  This is especially bad for 
people who are awaiting events in March, though in later months, people 
will have already adjusted to the change.

And what about those who are born on the 29th February?  Do they have to 
wait four years for their next birthday?  I don't believe I have never met 
anyone born on this day, but if one of those people is reading this 
article, I would very much like to hear from them!

In fact, the idea of having "leap years" was thought up to offset the 
difference between the normal calendar year of 365 days, and the solar 
year, which is roughly a quarter of a day longer.

If the current, or any other, year is a leap year, it must be divisible by 
four, but not by one hundred.  The exceptions to this are those years that 
are divisible by four hundred.  This means:

          a) 1996 was a leap year [1];
          b) 1997 is most definitely not a leap year; 
          c) 1998 will not be a leap year;
          d) 2000 will be a leap year; and
          e) 2100 will not be a leap year [2].

This author wishes he could write this article on the 29th February, but he 
cannot be bothered to wait until the year 2000.

[1] Think back; it wasn't that long ago.
[2] Of course, this hardly seems to make a lot of difference to anybody
    alive at this moment, as most of them stand little or no chance of ever 
    seeing the year 2100.
