In some ways it's overkill, but you may find it useful to use the DataTime
module from CPAN to handle your dates. This then allows you to create a date
object, add your increments easily (correctly handling leap years etc) and
compare that to see if you've over-stepped your final date.
You can find it here:
It is a large module that takes up a fair amount of memory. But it gets it
right, including leap seconds, missing days centuries ago etc.
All the best,
