I recently switched my offsite schedule to an every-other Tuesday schedule and I’m having difficulty calculating a valid return date for that scenario.  How do I know if any given Tuesday in the future falls on a service date or not?

I’m running Solaris and I have the Date-Calc package by Steffen Beyer, but I haven’t found an example of how to solve this particular problem and I haven’t learned perl well enough yet to figure it out on my own – has anybody solved a problem like this?

Thanks,

Neil
