When do my form views get reset for the month?

This is my first month using jotform, and I have created a few forms to be used on my website. My first form was created on the 16th of September it says. However now it says i have exceeded my views for the month and it is the 20th of October. Just wondering why my form view for the first month has not been reset back to 0? Does this go by calendar months? (e.i. September, October)

Thanks for your time
