When does my account begin and end?

It says I've exceeded my use, but I don't understand how. I feel like I must not know the full details of my monthly renewal. 

I see that your account ryanagrimson is currently holding Free subscription and has received 240 submissions and 1300 form views for the current month. Please be noted that the Free accounts are limited to receive only 100 submissions and 1000 form views in a month. Since your account has reached the limits, it has been tagged as overlimit and the forms are disabled. In order to continue to receive more submissions, it is required to upgrade your account to a paid plan or wait for the submission counter to reset on the first day of the following month.

Hope this information helps!
