A Doptim algorithm to find missing dates


Doptim's research teams have developed a unique prediction algorithm capable of providing you with estimates for missing dates in your genealogy. This algorithm processes birth, marriage, and death dates, as long as they are not certain (e.g., "calculated," "approximately," "between... and...," etc.). To access it, click on the "Date Estimator" tool.

We do not make predictions for people in your tree born after 1900. So, it's impossible to predict your death date... or that of a loved one!


Check the Birth, Marriage, or Death boxes to display predictions for the dates you want to work on. You can sort the information.
