2. The billing date of ICBC credit card is 1. The repayment date of ICBC's credit card is 25th. Credit cards have an interest-free period: the current month's consumption can be returned before the 25th of next month. For example, if you spend money in 500 yuan in March 1, it will be interest-free on April 25th. The longest interest-free period is 56 days. I bought it in 800 yuan on March 3 1 and returned it before April 25. The shortest interest-free period is 25 days. Therefore, the 5,000 yuan you spent on October 5th, 65438 has passed the billing date (June 30th, 65438), so the repayment date of this consumption is before October 25th, 65438.
