The longest interest-free period of CITIC Bank credit card is 50 days. Generally, you can enjoy the longest interest-free repayment period by swiping your card on the second day of the billing date. For example, someone's credit card billing date of CITIC Bank is 1 day per month, and the repayment date of the bill is delayed by 19 days, which is the 20th of each month. If the cardholder makes credit card spending on the 2nd of the current month, the spending on the 2nd will be included in the next month's bill, with a time span of 1 natural month, and the last repayment date of the credit card will be postponed by 19, so the spending on the 2nd can enjoy a maximum interest-free period of 50 days.
