Awstats in sync with DH "month"

I searched, but didn’t see this covered.

I’ve installed awstats on several domains and all is good. Except… it seems to be working off the calendar month and obviously my DH account is not on the calendar month (meaning my account renews on like the 10th, instead of the 1st).

Is there anyway to reset awstats so it begins the “month” at the same time as my DH account? Even if it has to be manually adjusted the first time, like today is Day 1 of a new billing cycle, so what could I change on awstats to have it reset today?
