You will be billed on a monthly basis based on the date you have started your subscription.
For example, a customer with a monthly subscription set to cycle on the 2nd of the month will always be billed on the 2nd.
If a month doesn’t have the anchor day, the subscription will be billed on the last day of the month. For example, a subscription starting on January 31 bills on February 28 (or February 29 in a leap year), then March 31, April 30, and so on.
