In this video I demonstrate how to perform calculations on dates before 1900. As you may know Excel does not recognise dates before the 01/01/1900. However if you add 1000 years to a pre 1900 date you will get a date that Excel does recognise.

Table of Contents:
00:00 Introduction
00:28 Add a 1000 years to a recognised date using EDATE
01:01 Add a 1000 years to a pre 1900 date
03:06 Calculate difference in days between two dates
05:22 Calculate difference in years between two dates
06:31 Calculate difference in months between two dates
