Countifs with nest left

hi im trying to do a count if with two dates, but i need to add a left formula and the dates im counting has a time after it and the date im using as a reference doesnt.

Here my formula which would work if the dates im looking up didnt have time in the same cell.

=COUNTIFS($A:$A,H3,$B:$B,H3,$C:$C,I3)

I have also attached the example.

I know how to do left and right but i dont know where to put it within a formula.
