I am making a subscription software billing reminder. We have software that we have like 400 users of, and we bill them on the anniversary of their signing up. We need to just remind them the day their bill is due, the same day every month.
the problem is that just changing 01/31/07 to 02/31/07 is just that, there is no 02/31/07.
Does perl have a way to just add one month to a date and be calander aware?

If so, how does it know on 02/28/07 when the cron job runs and sees that date, that next month it needs to set it not at 03/28/07, but to 03/31/07?

Thank you very much for your insight.
