According to my credit card experience, the credit card billing date refers to the day when the bank settles the credit card user's account, while the credit card repayment date refers to the day when the user must repay before this date, otherwise it will be overdue. Repayment between the billing date and the final repayment date is not overdue, and repayment during this period can directly enjoy the longest interest-free period of the bank. It is recommended to spend on the day after the billing date to avoid overdue due to different banks. The above is the information I know, I hope my answer can help the landlord!
