Most of the scripts I've seen keep a running total of the last 30 days.

What is the problem you're trying to solve?

If you want to take a snapshot on the tenth of each month for billing,
then just run a cron job to capture the data on that day.

If instead you want to clear all of the accumulated samples so that the
calculations begin fresh on the tenth, then you probably want to rotate
out your logged data to a different file on the tenth of each month.
This would cause the script to start with zero samples at the rotation

Either of these sounds like a trivial exercise using cron.
