Calculation Example

We are going to have to find out the age of a couple of our relatives so they know exactly how old they are. We can use this tool to help us do that. First, our relative was born on 4/12/1959, so we will choose that date from the date of birth field. We can hit calculate and learn that their age is 65 years, 8 months, and 6 days old, or a total of 23,992 days. Our other relative was born on 8/8/2008. We can now enter that date of birth into the field and hit calculate to get an age of 16 years, 4 months, and 10 days, or a total of 5,976 days.
