What are partial month charges?
Partial month charges usually relate to new services. Your billing works in "cycles" – your own cycle begins on a certain day of one month and continues for 30 days. If your billing cycle begins on the 15th of a month, but you signed up for service to begin on the 5th of the month, you’ll pay for 10 days of "partial month service." Then, your charges for those ten days are "prorated."
