a credit card only needs to be repaid on the last repayment date. I used a CCB credit card. Credit cards have a fixed billing date every month, and 2 days after the billing date is the final repayment date. Before the final repayment date, they will be repaid in full according to the bill amount, and consumers will enjoy an interest-free period. If you don't repay in full on time, the consumer will not enjoy the interest-free period, and the bank will charge interest in full at five ten thousandths of a day from the date when your consumption is recorded. \xd\ For example, if you spend money by credit card on January 27th, you will settle your account on February 25th (assuming February is 28 days), and the due repayment date is March 17th. \xd\ If you want to enjoy the longest repayment period of 5 days, you can swipe your card the day after the billing date of each month, that is, swipe your card on 26th of each month, for example, swipe your card on 26th of March, and settle your account on 25th of April, so it has been 3 days, and the due repayment date is 15th of May, so the total * * * is 5 days. \xd\ If you swipe your card on the billing date, the repayment period is only 2 days, such as swiping your card on April 25th, closing the account on April 25th, and the due repayment date is May 15th, so the total repayment period is 2 days.
