For purchases made by card on the 22nd, if it is domestic consumption, the credit date should be the 22nd or 23rd, so the settlement will be on the bill on the 23rd of the month, and the due date of repayment is 20 days after the bill date. For example, if you make a purchase on April 22nd and settle the bill on April 23rd, the due date for repayment is May 13th.
If you swipe the card on the 22nd, you can only enjoy the 21-day repayment period. If you want to enjoy the maximum 50-day repayment period, it is recommended to swipe the card on the day after the monthly bill date, such as swiping the card on April 24. The settlement is on May 23, and the payment due date is June 12. From April 24th to June 12th, there are exactly 50 days.
