Possibly a Count function?

I have a sheet of data with 6 columns;

ID
Surname
First Name
Job Status
Time
Date

The date shows each time someone has checked in to our building but I would likd to count the data to see how many times each person has checked in (there is approximately 600 different people). I obviously dont want to have to do this with givin the sum a surname, i was hoping there might be a way to do it automatically.

Thanks

Drop it into a pivot table with a COUNT aggregation.

Can someone point me in the right direction for the Count Aggregation

Drag the date person name in to the column pane, and the date into the value pane. The date aggregation should default to count.
