Each CCB credit card has a billing date (it will be written in the card letter sent to the landlord's credit card, or you can enter information through his credit card website-"Credit Card Service Hall" on the left), and the due repayment date is 20 days after the billing date. As long as the payment is made in full according to the bill amount before the due repayment date, the consumption part can enjoy interest-free treatment.

Suppose: the landlord's billing date is 10 every month, then the transactions such as credit card consumption and cash withdrawal from 10 to the next month 10 will be settled on10, forming a billing cycle, and the due repayment date is 20 days after the billing date, that is, the 30th of the next month.

Furthermore, I want to give some advice to the landlord. The closer the general bill is to the future bill date, the longest repayment period can be enjoyed (that is, the interest-free period said by the bank, as long as the landlord pays back the money in full according to the amount written on the bill, the credit card will not charge interest). Specifically, when the accounting date is 10, it is assumed that the landlord is 4/ 1 1.
