countif wildcard

I need to count occurrences of a cell containing an appt time vs. blank.

Not all cells in the range contain a time, but I need to count how many appts occurred, thus having a time (ex. 2:00 PM) in any of the cells.

i tried
countif(A1:A25,"*:")

doesn't work

Any suggestions would be greatly appreciated.

Times are just formatted numbers in Excel so the : is part of the formatting not the underlying value.

Try just

=COUNT(A1:A25)
