According to Wismai Finance Network, credit cards can be repaid on weekends, and there are many repayment methods. In some banks, the bookkeeping date is the 20th day after the bookkeeping date, as long as it is handled at the counter of the bank branch. Personal affairs are best paid on weekdays from Monday to Friday. For large bills, you can choose to repay them in installments or delay the credit card for a long time.
