Return money to others according to the Gregorian calendar

Actually, there's nothing to say about this. Morning and evening are fine. I thought there was a saying "I have to pay it back sooner or later".

Maybe you have some local customs, or you wouldn't have imagined such a statement out of thin air. I suggest asking the old people around you, or directly asking each other, do you mind the time to pay back the money? You can refer to each other's time requirements.
