The credit card repayment date is18th day after the bill date. Suppose the billing date of the credit card is 1 (fixed) every month, and the repayment date is18th day after the billing date, that is,19th every month.

In other words:

September 2-65438+1 October 1 credit card consumption, June 65438+1October/bill, and repayment before June 65438+ 10/9.

65438+1 October 2-1 65438+1credit card consumption, according to 65438+1October1accounting,1650. And so on.

Therefore, if you swipe your card on the day of the bill, the interest-free period is the shortest, only 18 days (10, 19), and if you swipe your card after the bill, the interest-free period is the longest, only 50 days (10, 19). Be sure to know the billing date and repayment date of your credit card so as not to miss it.
