Will this formula calculate thee number of different days worked?

Column L contains the day but will have multiple entires of simular dates.

EX: each employee, Column j could have, for example 8 items listed on Nov
16, 6 on Nov 15, etc. In this example I need to calculate that he only worked
2 days

Thanks

...
Column J= employee number
Column L = day(s) work

I need to sum the number of different days worked by each employee (Column
L
can have multiple instances of the same date)

Thanks
