The final repayment date of ABC's credit card is the 25th day after the billing date, and your billing date is the 7th day of each month (fixed), that is to say.

Generate a bill 10.7, and record the transactions in the period of 9.8- 10.7. The final repayment date of the transactions in this period is the 25th day after1.1

Generate a bill 1 1.7, and record the transactions during the period of10.8-1.7. The final repayment date of the transactions during this period is the 25th day after 1 1.7, that is.

And so on.

Obviously, 10.7 on the billing date has the shortest interest-free period of 25 days (10.7, 1 1), and 10.8 on the first day after the billing date has the longest interest-free period of 56 days (10.8). Credit card full repayment before the final repayment date is interest-free. It should be noted that credit card consumption has an interest-free period, and cash withdrawal has no interest-free period.

If you have other specific questions, I suggest you call the customer service staff of the bank, hoping to help you.
