The "fishy" part is that years divisible by 100 aren't leap years,
whereas those divisible by 400 are. So 1700, 1800 and 1900 weren't
leap years, but Y2K will be.

In that case, I suggest enhancing the above pseudo code as follows: :-)
function isLeapYear(year as int) as boolean
if ((remainder(year div 400) = 0) or (remainder(year div 100) <> 0 and
remainder(year div 4) = 0)) then
return true
else return false
end
