Membership Billing Question

Hi,

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?

Cheers
