You are talking about a hypothetical question, right?

Because: It is only September 2nd, not September 6th yet, and the shortest interest-free period for credit cards is 18 days. In other words: based on the billing date you mentioned, the repayment date should be No earlier than the 28th.

Let me explain to you the credit card repayment rules:

Consumption before the bill date will be included in the current bill, and it should be paid off in full before the current bill repayment date; consumption after the bill will be included in the bill. It will be included in the next bill and should be paid off in full before the due date of the next bill. Consumption on the billing day is divided according to the settlement periods of different banks and different merchants. It may be included in the current bill or the next bill. Under normal circumstances, transactions before 21:00 on the billing day will be included in the current bill. However, it may also happen that the settlement time of some merchants is 23:00, resulting in all transactions before 23:00 on the billing day being included in the current bill. middle.

So, according to your description, the one thousand yuan paid on September 6th was included in the September bill and should be paid off in full on September 19th.
