If the credit card has a grace period for repayment, and the grace period is greater than one day, then the repayment date of the credit card can be repaid on Monday of the weekend, and the repayment on Monday happens to be within the grace period. Credit cards have no grace period for repayment, and users must repay on the repayment date. If the repayment date is Sunday, the repayment funds must be paid before 24 o'clock on Sunday.

Even if the user repays on the repayment date, but the repayment funds arrive late, the system will calculate the overdue repayment of the user based on the time when the repayment funds arrive.
