For those without a date calculator, you simply subtract the age from the date of death, *matching* month/day/year. Since the death date was Oct (10), 20, 1854 and she was 1 month, 2 days, and 71 years, subtract 1 from 10 to get 9 (or Sept.), 2 from 20 to get 18 days, and 71 years from 1854 to get 1783 (year) making her likely birth-date: September 18, 1783. If you need to *carry over* sums so you can subtract, you just need to remember to convert 1 year to 12 months and 1 month to 30 days For example: if a death date is 4th August 2000 and the age at death was 50 years, 10 months, 10 days your figures would look like this: 8 mo 4 day 2000 yr (date of death) - _10 mo 10 day 50 yr_ (age) Since the top numbers are smaller, you must do some converting. You subtract 1 year from 2000 so it becomes 1999, then add 12 months to the 8 (because there are 12 months in a year - you are just moving a year from *year* to *months*) which gives you 20 months. Of course you now also need to move a *month* over to *days* so the number of months becomes 19 and the number of days becomes 34. There is of course possibility of error here as one would need to be aware of leap years and also adjust for the number of days in a particular month (which I didn't) but you would at least have a *ballpark* figure of a birth date with-in a couple of days of the real birth date that should make hunting down birth information easier. You are now subtracting as follows: 19 mo 34 days 1999 year - _10 mo 10 days 50 years _ 9 mo 24 days 1949 tears So this fictitious person would have been born on or near the 24 of Sept in 1949. I hope this isn't too confusing! You can of course also use this method to calculate age if you know the date of death and the date of birth. We used to use this in the school where I worked to determine as closely as possibly the age of a child at the time of being given a certain test. Being aware of doing this the *long way* with-out aid of a computer program might come in handy if you are researching somewhere where computers are not available and *need to know*! Of course if there is a computer handy and a conversion program, all the better!
