Membership Billing Question


I’m just wondering how membership billing works.

Is it from the start of the month like market data or is it from the date you purchased?
If I purchased a yearly membership would it be from Jan 2022 to December 2022 or Aug 2022 to Aug 2023?
If I purchased one month of membership on the 5th, would monthly be for 5th Aug to 5th Sep or 1th Aug to 1st September?
