the billing date and repayment date of ICBC credit cards are fixed, that is, the 17th of each month is the billing date and the 1th of each month is the repayment date. On the billing day, the bank will count the credit card consumption bill from 17th of this month to 16th of next month, and send the bill to the cardholder. Therefore, on the 17th billing day, the cardholder may receive a short message from the bank on 18th, informing him of the amount of this month's bill and the minimum repayment amount.
