Generally, the billing date and repayment date are twenty days apart.

when the user modifies the billing date, the repayment date will also change. That is, because there is an interval between the repayment date and the billing date, users can extend the interest-free period by controlling the consumption time.

when the user continues to spend money after billing, the consumption amount will be included in the next bill, so that he can enjoy the longest interest-free period. Of course, users must repay in full to enjoy the interest-free period, and they can choose the minimum repayment or installment repayment, but they all need to pay extra fees.
