The repayment date of Bank of Communications credit card is the 25th day after the bill date. Suppose your credit card billing date is 1 1 (fixed) every month, and the repayment date is the 25th day after the billing date, that is, around the 6th of every month (there are 30 days in a month, 3 1 day), that is:

May1February-June 1 1 is a billing cycle, and the credit card consumption in this cycle will generate a bill on June 1 1, and July 6 is the final repayment date.

June1February-July 1 1 is a billing cycle, and the credit card consumption in this cycle will generate a bill on July 1 1, and August 5 is the final repayment date. And so on.

Therefore, the shortest interest-free period for credit card spending on the day of billing is only 25 days (June 1 1 credit card spending, repayment on July 6), and the longest interest-free period for credit card spending after billing is 56 days (June 12 credit card spending, repayment on August 5). Be sure to know the billing date and repayment date of your credit card so as not to miss it.
