google sheets filter formula before and equal to date not including last date

I have created a formula to filter data before and equal to a date, however it is including every date up to and not including that one. What am I doing wrong? The formula:

=FILTER(A:F,F:F>=C8,F:F<=D8)

Thanks for any help

>Solution :

Change F:F to

arrayformula(int(F:F))

you probably have also hours in column F
