    How does Rogers Internet calculate their months?

    It's the first day of September, and I just a notice from Rogers saying that I used 75% of my monthly internet usage. Huh? The month just started and the only thing I did was go on the Yahoo!. So I'm guessing that they're still on previous month and I'm wondering when the 'Rogers' month will end.
