Counting date entries in csv spreadsheet

I have entries similar to the ones below. I have 1500 rows of data. Out of this, all I care about is how many entries I got each day. So for 8/19/2025 id like it to return 2, 8/20/2025 it returns 4 and so on. I was going to do a countif command using =COUNTIF(B2:1479, 8/19/2025) then =COUNTIF(B2:1479, 8/20/2025) but it returns 0 for both. I assume its looking at the time in the value so it does not meet the criteria.
