The shortest interest-free period of CCB credit card is 20 days and the longest is 50 days. The final repayment date of CCB's credit card bill is the 20th day after the bill date. You said that your bill date is 19, so the final repayment date is probably the 8th or 9th of next month.

For example, it is calculated as follows:

The consumption from April 20th to May 19 is the bill accumulated on May 23rd, and the final repayment date of the bill is June 8th.

The consumption from May 20th to June 19 is the bill accumulated on June 23rd, and the final repayment date of the bill is July 9th.

After the monthly bill is settled, CCB will send it to you. I suggest you pay attention. You can edit the short message with the mobile phone reserved by the bank and send "4 digits after CCZD# card number" or "4 digits after 3 1 1# card number" to 95533, so that you can check the bill date and repayment date.
