As a Pley member, the renewal or billing date is the day you are billed each month. Your billing cycle begins on the date of sign up and will renew on the same day of each month thereafter.
Example if you sign up on July 1st, your next billing renewal date will be August 1st and so on.
This information can be found by signing in to your account then under "Settings" then "Account Settings"
Current period ends: This date is the date your billing cycle ends, this date is one day prior to your renewal date, so this means the following day your subscription will be billed.
Example using the above scenario, your current period would end on July 31st one day prior to the renewal of August 1st.
