[excel] How many times does each value appear in a column?

I have a column with time data like this:

17:27:31
17:27:32
17:27:32
17:27:33
17:27:33
17:27:34
17:27:34
17:27:34
17:27:35
17:27:36

I want to count how many times each value repeats:

Value      Count
17:27:31   1
17:27:32   2
17:27:33   2
17:27:34   3
17:27:35   1
17:27:36   1

How can I do such a thing?

You can use CountIf. Put the following code in B1 and drag down the whole column

=COUNTIF(A:A,A1)

It will look like this:

The quickest way would be with a pivot table. Make sure your column of data has a header row, highlight the data and the header, from the insert ribbon select pivot table and then drag your header from the pivot table fields list to the row labels and to the values boxes.
