Credit cards are divided into billing date and repayment date, generally 20 days apart, with billing date in front and repayment date behind. The next day's repayment and the same day's repayment are included in the next month's billing date. Therefore, it is ok to pay it back one day before the repayment date and take it out the next day, and you can take it out the same day. This month's repayment has been completed, and the money withdrawn will be paid back next month.
