The final repayment date of ABC's credit card is the 25th day after the bill date. For example, suppose your credit card billing date is 16 (fixed), that is,

The bill 10. 16 was generated, and the transactions during the period of 9.17-10. 16 were recorded. The final repayment date was the 25th day after/kloc-0.16.

A bill 1 1. 16 was generated, and the transactions during the period of10.17-1.16 were recorded, and the final repayment date was/kloc.

And so on.

Obviously, 10. 16 has the shortest interest-free period of 25 days (10. 16, 1 10), and the first day after the bill date is10. It should be noted that credit card consumption has an interest-free period, and cash withdrawal has no interest-free period.
