Hello, if you hold a China Merchants Bank credit card, the interest-free period refers to the time period from the bank bookkeeping date to the due repayment date when the credit card holder repays all the due amount before the due repayment date (inclusive). The longest interest-free repayment period is 50 days, unless otherwise agreed between the card issuer and the applicant, but the longest interest-free repayment period shall not exceed the longest interest-free repayment period required by relevant laws and regulations (except cash advance).

Credit card repayment is also periodic. "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 8th of each month is the bookkeeping date, the 28th of each month is the repayment date, and the consumption from the 8th of last month to the 7th of this month is repaid on the 28th of this month.
