First, credit cards are generally consumed on the bill date, with the shortest interest-free period;

2. You can enjoy the longest interest-free period if you spend on the day after the bill date;

For example, the billing date of China Merchants Bank Credit Card is 20th of each month, and the repayment date is 8th of each month. Therefore, if you spend money on July 20th, which belongs to the bill of July 20th, and you have to repay it before August 8th, then you can enjoy the shortest interest-free period.

If it is July 2 1 consumption, which belongs to the bill of August 20, it should be repaid before September 8, so that you can enjoy the longest interest-free period.
