Tip: To calculate elapsed month, you can use this formula =DATEDIF(A2,B2,"m"), A2 is the start date, B2 is the end date. For elapsed years, apply =DATEDIF(A2,B2,"m")/12, and then format the cells as number.

Calculate elapsed year, month and days

For example, you have two dates, and you want to know the exact difference between these two dates, and display the elapsed period as x Years, x Month, x Days (such as 2 Years, 6 Months, 19 Days), you can apply below formula.

Select a blank cell which will place the calculated result, enter this formula =DATEDIF(A2,B2,"Y") & " Years, " & DATEDIF(A2,B2,"YM") & " Months, " & DATEDIF(A2,B2,"MD") & " Days", press Enter key to get the result.
