Resources for tracing your Family Tree and Ancestry

I created this tool to calculate a date based on how long ago it was. This is useful when you see a tombstone, for example, that gives the death date and the age in months, years and days, but leaves it to you to calculate the birth date. You can also use it to estimate a birth date when given an age on a given date. It is basic math but it can sometimes be very confusing, so this was made to help.
