Three to five days. According to official website of CITIC Bank, the grace period of CITIC Credit Card is usually three days. If the cardholder completes the repayment within 3 days after the repayment date, the bank will regard it as timely repayment, which will not generate overdue interest and will not affect personal credit information. Repayment must be completed before 20:00 pm on the last day of the grace period. If the cardholder needs to extend the grace period, he can call the credit card customer service hotline of CITIC Bank to apply. Under special circumstances, the grace period can be extended to 5 days.
