This operation is correct.

The repayment cycle of a credit card usually follows the rules of "bill date" and "repayment date". When a user makes purchases using a credit card within a month, these purchases will be recorded on the credit card statement.

The billing date is the date when the bank generates a statement for the user's credit card account, and the repayment date is the date when the user needs to repay the minimum payment amount shown on the statement or the deadline for full repayment. For example, if the user's credit card bill date is the 5th of each month, the repayment date is the 25th day after the bill date.

Please note that the billing date and repayment date of each bank may be different, and the specific dates should be clear in the user's credit card contract or the information provided by the bank. To avoid late repayments, it is recommended to check your credit card statements regularly and ensure that repayments are completed before the due date. Late repayments may incur additional fees and affect the user's credit history.
