Hi,

Here is a formula solution..

=SUM(IF(FREQUENCY(IF($B$2:$B$27=D2,IF($A$2:$A$27<>"",MATCH($A$2:$A$27,$A$2:$A$27,0))),ROW($A$2:$A$27)-ROW($A$2)+1),1))

where D2 holds "a"

It's an array formula. Confirmed with CTRL + SHIFT + ENTER.

do you know how to create a pivot table?  That should be able to give you a breakdown of all employees and the days they worked.

How do you need to use this days-worked count? (in code, in formula, other)
