Consumers enjoy the shortest interest-free period on the day of billing; Consumption on the first day after the bill date enjoys the longest interest-free period.

1. The credit card billing date means that the issuing bank collects and settles all the transactions and expenses of your credit card account in the current period on a regular basis every month, calculates the total amount owed and the minimum repayment amount in the current period, and mails the statement for you. This date is the billing date of your credit card;

2. For credit card non-cash transactions, the interest-free repayment period is from the bank bookkeeping date to the due repayment date. The interest-free repayment period varies according to the regulations of each bank. The shortest is from the billing date to the final repayment date, and the longest is from the day after the billing date to the final repayment date of next month. If the billing date is 1 day and the final repayment date is 20 days, the shortest is 20 days and the longest is 50 days.

If you have other specific questions, I suggest you call the customer service staff of the bank, hoping to help you.
