The billing date and repayment date of a credit card can be changed, but there are two situations due to different bank policies.

First, the number of days specified up and down changes; Ex.: The 5th bill will be repaid on 25th. If the 6th or 7th bills change, the repayment date will remain unchanged, and so will the repayment date.

The second is to change the fixed corresponding date. For example, bills on the 5th, bills on the 25th, and bills on the 30th, 10 days, must be repaid. However, according to a fixed bank, the interval is not fixed at 20 days, and the general interval is 15~25 days.

The specific bank modification method shall be subject to consulting the manual customer service of the issuing bank.
