[Counting the Cost: How Many Days Interest on Forex Open Positions- Sep 2023]

Hello, i have 2 questions about this:

1) in terms of the practicalites, does this mean that if i had a position in AUDCAD opened at 9am on 6 Sept and closed at 9pm that day, i would incur no interest rate costs, whereas: if i closed it at 11pm on the same day i would had a 3 day interest rate charge?

2) why do you charge interest in this lumpy way rather than spreading the weekly cost uniformly across the 5 trading days?

Thanks
