According to the calculation rule that the due repayment date of CCB is 20 days after the billing date, the due repayment date of the landlord is 25 days, and the billing date should be 5 days of each month. Therefore, the credit card consumption and cash withdrawal transactions from the 6th of each month to the 5th of the following month will be settled on the 5th of the following month, forming a billing cycle.

That is, the transaction of 1/6-2/5 is settled on the bill of 2/5, and 2/25 is the due repayment date.

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 mentioned by the bank, as long as the landlord repays in full according to the amount written on the bill, no interest will be charged for the credit card). Specifically, in the case that the bill date is 5th, assuming that the landlord swipes the card 1/6, then this credit card is settled at 2/5 of the bill.

If the landlord has other questions, you can ask.
