Let's take a credit card as an example. It's good to repay on the repayment date of the credit card. If it's because credit card repayment usually arrives immediately, that is to say, as long as the repayment is made before 24 o'clock on the repayment date, then you are not overdue.
In addition, according to the relevant provisions of China Bank Card Industry Self-discipline Convention, from July 1, 213, banks should provide tolerance and time-tolerance services to credit card holders: if the cardholder owes less than 3 days and the amount owed is less than 1 yuan, it will be regarded as timely repayment, and the bank will remind you 3 days before the due repayment date of the credit card; Therefore, if you don't pay back the money on time, there is also the "time-tolerant" service of the bank to escort you; The grace period for repayment of credit cards of China Merchants Bank, China Construction Bank, Guangfa Bank, Shanghai Pudong Development Bank, CITIC Bank, Xingye Bank and Ping An Bank is 3 days; The grace period for repayment of Bank of Beijing and Agricultural Bank is 2 days; However, different banks have different regulations, so I suggest you ask the issuing bank for specific regulations.
