How to calculate the repayment date when the credit card billing date of China Construction Bank is 10?

It's simple. The final repayment date is 20 days after the billing date of CCB's credit card, that is, 30 days, billing will be made on the 30th of each month, and repayment will be made on the 30th of each month (two days will be postponed automatically in February). CCB has a short message reminder of repayment 3-5 days before the repayment date. You can also pay attention to WeChat (scan the QR code of official website WeChat), bind credit cards, check bills, details, points and limits, and give free reminders for pen transactions.
