This is actually very simple, just remember that the expiration date of the Bank of Communications credit card is 25 days after the bill date.

Note: the bookkeeping date is 10 day per month, and the due repayment date is the 5th of next month.

In addition, there is an interest-free repayment period, from the bookkeeping date to the due repayment date. The longest interest-free period of Bank of Communications credit card is 56 days and the shortest is 25 days. The interest-free period is different on different credit card dates, and the longest interest-free period can be enjoyed on the day after the bill.

For example, your billing date is 10 every month, and the 25th day after the billing date is the due repayment date. If you spend in May 10, the billing date is May 25th, and the interest-free period is only 25 days (May10-May 25th). If you spend in July 1 1, the bill will be paid in August 10. Your final repayment date is September 5th, and the interest-free period is 56 days (July11-September 5th).

Now you should be able to understand. If in doubt, you are advised to consult the bank customer service staff directly.
