The interest-free period of Bank of Communications credit card is 25-56 days, and the day after the bill date is the longest interest-free period. According to the cardholder's spending time, the interest-free period will naturally be different.

Suppose the monthly billing date of the credit card is 18, and the final repayment date of the next month is 13:

Consumption time with the shortest interest-free period: If the cardholder spends money on this month 18 and records the arrears on the same day, then the interest-free period enjoyed by the cardholder is 25 days from this month 18 to the next month 13;

Spending time for enjoying the longest interest-free period: If the cardholder spends money in this month 19 and the debt is recorded on the same day, the interest-free period enjoyed by the cardholder is 56 days from this month 19 to the second month 13;
