Bookkeeping day means that all your previous expenses will be booked on this day, and then you have to pay off the money you owe within the specified time. It's not that you can continue to use your money on the billing day, whether you haven't paid it back yet. If your total amount is 50,000 yuan, and you have spent 49,000 yuan, then your remaining available amount is only 1000 yuan, regardless of whether the bill has been paid off, or you have only paid off a part, such as 49,000 yuan, but only 29,000 yuan, so before you pay off this money, your remaining available amount is 265,440 yuan. It doesn't mean that your quota will be restored as soon as the billing date is over. Whether it will be restored depends on whether you have paid back the money and how much. The bank only provides an interest-free repayment period for a period of time, during which you can spend with your credit card without interest.
