The Calculate Estimated Dates tool Addon is used to add and remove birth and death events for people that are missing these events.
You can select the tool via the menu Tools->Family Tree Processing-->Calculate Estimated Dates... this brings up a Undo history warning window:
You then choose Stop or Proceed with the tool.
You will be presented with the Calculate Estimated Dates tool window. This window initially has two tabs:
- Go to the Options tab
- Check the [ ] Remove option to remove previous estimates
- Select the Add date options to date events with or without dates
- Click on Execute
- Select the people with which to add events
- Click on Add Selected Events button to create
If you decide to make an event permanent, remove it from the Source. Otherwise, it will get removed the next time you automatically remove these events.
You may have to run the tool repeatedly (without removing previous events) to add all of the events possible.
On the Select tab you will see the processed results if any.
You can individually select the checkbox(s) beside the people or Select All and then click on Add Selected Events button to create the new events shown.
