Calculate the difference between multiple calendar data

[Hansulet]

I need to find out the result of difference between multiple calendar data.

For example I need to calculate in years, mont and days the sum of column C

A1 B2 C3
01.08.1997 10.08.1999 2 years and 9 days
15.08.1999 02.05.2008 8 years, 8 month and one day
03.05.2008 16.11.2018 10 years, 6 months and 15 days
