Generally speaking, there is a principle for customers to change the billing date of credit cards, that is, after the bill is changed, the original bill on the 20th will not be issued, and the current billing cycle will be extended to the new billing date 15, that is, the billing cycle will be extended by 25 days, so the consumption from March 2/kloc-0 to May 15 will be in May/kloc-. There will be no interest and other expenses.

Because changing the billing date is equivalent to allowing customers to enjoy more interest-free period, which is not conducive to banks. Therefore, under normal circumstances, the bank will limit it to three months or six months before changing the billing date.
