Let’s take the example of CCB credit card and talk about the billing date and repayment date. The longest interest-free period for CCB credit cards is 50 days, and the shortest is 20 days, that is, the repayment date is the 20th day after the bill date. The billing date is the 18th, and the repayment date is the 20th day after the billing date, that is, around the 8th, the card consumption from October 19th to November 18th will be billed on November 18th, before December 8th Just repay it. Card purchases made between November 19th and December 18th will be debited on December 18th, and the payment can be made before January 7th. And so on. Therefore, if you swipe the card on the bill date, the interest-free period is the shortest, only 20 days (swipe the card on November 18 and repay on December 8). If you swipe the card on the bill date, the interest-free period is the longest, 50 days (swipe the card on November 19). , repayment on January 7).
