Well, basically, I don’t think it’s that difficult to determine people’s ages by knowing their exact and complete date of death and date of birth. Just subtract the larger year from the smaller one and get their approximate age ± 1 year, or if you want very accurate results, you can use a date calculator that will show you how old each of your ancestors is without any errors or mistakes https://www.calculator.io/date-calculator/ .
