Ok, I'm not sure what your program is doing, but it would seem that for some reason you need to record info based on the date... or perhaps a perpetual calendar.

I think that the most obvious suggestion for this is to search CPAN to see if there is a pm written to do this for you. You seem to want to record something on a day to day basis and then output a summary of the past month's information or something?

You can create a simple data structure to handle this and code to perform the summative functions over it.

One potential way to do this is to make a database hash (thus saving the information to a file) based on the date, and create the summative information over a months worth of info. I'm not going to write out code for you to do this as it sounds like you're getting paid for this, and I'm not, and since realistically speaking, I only have a vague idea of what you are trying to do.
