Hello!

For example: 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 28th, and the repayment date is the 20th day after the billing date, that is, around the 18th (because it spans the end of the month, and there are 30 and 31 days in each month, so it is not fixed, but I don’t know how you say the repayment date is 8th), that is to say:

Card consumption from October 29th to November 28th will be debited on November 28th, and you can repay it before December 18th. (Before 24:00 on the 18th)

Consumption by card from November 29th to December 28th will be debited on December 28th, and you can repay it before January 17th. And so on.

So, if you swipe your card for consumption on the bill day, the interest-free period will be the shortest, only 20 days (swipe the card on November 28, and repay on December 18). If you swipe your card for consumption on the bill date, the interest-free period will be the longest, 50 days. days (swipe the card on November 29 and repay on January 17).

Hope this helps.
