CCB provides credit card repayment grace period service for 5 days (due repayment date T+5), and repayment within the grace period is regarded as timely repayment. For example, the final repayment date of your credit card bill in CCB is 65438+1October 22, so your repayment only needs to be received before 65438+1October 27, and CCB is deemed to have repaid on time in this period.
