Thanks for the info. Maybe I'll post it to the comp.lang.perl newsgroup once and see what they say. Maybe the developers monitor that newsgroup. If not, I'll email Flavio.

Thanks again.

While I'm at it, does anybody know of any other recurrence modules that are pretty advanced? Our recurrence handles yearly, daily, weekly, weekday a month, date a month and a few others. I have seen others, but they were limited. That's what I liked about the Date::Set module.
