The only difference between handling credit cards on weekends and from Monday to Friday is that the audit time is one more day. According to relevant public information, Sunday is not a working day, and the credit card approval time is calculated according to the working day. Doing a credit card on Sunday will give people a feeling that the approval time is too long. For example, the bank's credit card approval time is 3-5 working days. If you apply on Monday, the results will be obtained from Wednesday to Friday, and if you apply on Sunday, you need an extra day.
