The 50-day repayment date of credit card refers to the interest-free repayment period from the bank billing date to the due repayment date, which varies from bank to bank. The shortest time is 48 days for Ping An Bank and the longest time is 56 days for Bank of Communications.

Let's give an example. Suppose your bank has a 50-day interest-free period.

Suppose your bank's arrival date is 10 every month. Swipe your card once on May 9, and you must pay back the money within 20 or 25 days after May 10 (20 or 25 days depends on different banks, such as Bank of Communications, China Construction Bank and China CITIC Bank, the longest is 50 days).

Similarly, if you swipe your card in May 1 1, then from June 10, calculate how much money you swiped from May 10 to June 10, and within 20 or 25 days after June 10 (.
