I'm going around circles with this, but I know I'm missing something obvious.

I need to highlight a staff member's work birthday in a holiday spreadsheet.

Column A contains all the days for the year (i.e. 01/01/2016 to 31/12/2016) in a vertical list. (A18 to A382)
Column B lists the days of the week.
Column C is staff member 'XY' 's data

Row 2 contains the Start Date of employees, e.g. 27/06/2014.
Rows 3 to 16 contains other numeric data (days taken, sick days etc.)
Row 17 contains their name

Using Conditional Formatting, I need to highlight in Column C the cell that is XY's anniversary of starting work with us, so 27/06/16 if their start date was 27/06/2014. (It must just highlight and not change the values in the cell.)

Obviously I then need this to repeat for all staff (Column C to Column DA).

Please can anyone help before I lose my mind?
