Hello, if you hold a credit card of China Merchants Bank, the credit card has a designated billing date and repayment date, and the repayment has a cycle. "Bookkeeping date" refers to the date when the card issuer summarizes the accumulated outstanding principal of consumer transactions, principal of cash withdrawal transactions, fees, etc. Every month, calculate the interest and the amount that the cardholder should repay. "Due repayment date" refers to the latest date when the cardholder should repay all the payable amount or the minimum repayment amount stipulated by the card issuer (the consumption amount can be repaid before the due repayment date, and the credit card can be returned before 24: 00 at the latest). For example, the 5th of each month is the bookkeeping date, the 23rd of each month is the repayment date, and the consumption from the 5th of last month to the 4th of this month is repaid on the 23rd of this month.
