Utility for repeating dates

Hi all,

I am working on a project involving repeating dates. The user should be
able to select differents methods for specifying the dates. For example:
each second Tuesday of the month for the next 12 months. Or: the first
non-weekend day in the month for the next 18 months. For anyone familiar
with Lotus Notes: when a new meeting is created in Notes, there is a
window Repeat Options. If I could somehow copy that window, then I would
be golden.

Now, I was thinking that I am probably not the first one looking for
something like this. Therefore, I have done some searching on the
internet, but so far I have not found something useful. Hopefully, someone
on this list can point me in the right direction.

For your information: the functionality should be integrated in a
5250-application written in RPG. If there would be a utility written in
RPG, then that would be great. But it is more likely that there will be
utilities written in Java. In that case, it would be a real challenge to
integrate such a utility in the existing application, but I would
certainly give it a shot.

Thanks in advance for any suggestions.
