Hobby Phase's Edge Reuqest usage

Hello, the Edge Request limit for my project is about to be exceeded soon. When I access the billing page, they offer 100M Edge Reuqest on a monthly basis. I wonder when the update cycle is. For the Web Analytics that has already exceeded, the measurement has started again every November 1st. I wonder if it is the same for Edge Reuqest. Or do we start measuring 1 month based on the date we exceeded?
