The credit card billing date of ICBC is 1 every month, and the corresponding repayment date is 25th. Later, ICBC added a new billing date of 19 from 8th to 26th, and the corresponding credit card repayment date was 1 to 19 next month. Cardholders can take the initiative to apply to ICBC to modify the billing date and repayment date. It is best to set the repayment date one or two days after the monthly salary, which is convenient for capital turnover and financial management. However, it should be noted that the credit card statement can only be modified once a year.
