The credit card bill date refers to the date when the bank sends the credit card bill to the cardholder. After the billing date is determined, 20 days later is the repayment date of the credit card. Only the amount that has been recorded on the billing date needs to be repaid, and the part that has not been recorded in the current consumption bill does not need to be repaid in this period. At the same time, you can enjoy interest-free concessions when you repay from the billing date to the repayment date.
