The repayment date of Bank of Communications credit card is the 25th day after the bill date. The billing date is the 8th, so the repayment date is the 25th day after the billing date, that is, around the 3rd (it is not fixed because it spans the end of the month and has 30 days 3 1 day), that is:

Credit card consumption from March 9 to April 8, receipt on April 8, and repayment before May 2;

Credit card spending from April 9 to May 8 will be recorded on May 8 and repaid before June 3. And so on.

Therefore, if you swipe your card on the day of the bill, the interest-free period is the shortest, only 25 days (swipe your card on April 8 and repay it on May 2), and swipe your card after the bill, and the interest-free period is the longest, only 56 days (swipe your card on April 9 and repay it on June 3). The longest interest-free period of Bank of Communications credit card is 56 days and the shortest is 25 days.

The above is just an example. You should record your bill date and repayment date clearly, so as not to miss it and cause overdue bad records.
