the consumption date is the date of swiping the card, the billing date is the billing date after consumption, and the due repayment date is 19 days after the billing date (the 28th plus 19 days is the 27th).

the period from the consumption date to the due repayment date is called the repayment period. Credit card spending can be repaid interest-free, while cash withdrawal transactions cannot be interest-free.

every day in the repayment period is the repayment date, as long as you repay on a certain day. The last day of the repayment period is called the due repayment date. If the repayment is overdue or not, interest and late fees will be charged.

if the bill is consumed on the same day, it will be settled on the same day, and the repayment period is 19 days.
