I never really cared enough to ask anyone, but something like my cable bill is 98$ a month. Do companies (in general) consider a month every 30 days or every time the 14th comes around?
I did rent a car once during a time change and I only got to keep the car 23 hours. As another side note I have had drug prescripts that were 28 days was considered a month supply. The would be 4 weeks instead of one month. -- https://mail.python.org/mailman/listinfo/python-list
