Q. Is there an easy way to calculate how long in years and months the employees have been working for my company?
A. Excel can do that, as long as you’ve listed all the employees in a database. If so, place them in an Excel worksheet with their start date in one cell and end date (which would be the current date, I assume) in an adjacent cell. Then insert this formula (where the start dates are in the D column and the end dates in the E column):
=DATEDIF(D2,E2,"y") & " years, " & DATEDIF(D2,E2,"ym") & " months ".
Here’s what it looks like in Excel (color added for clarity):
Be sure to format the D and E columns to display dates (see screenshot below).
