Event filters for missing dates etc

I would like to find:

  • All events of a specific type that does not have a date
  • All persons that does not have at least one event with place and date

Are there any existing filters I can use for that? (I see some filter that does similar things, e.g. find persons that has any event without place and date.)

This is the easier item to find.

In the Events view, click on the title of the date column to sort by date. If the sort is low-to-high, the blank dated events will sort to the top. Now use the Filter Gramplet to find the Event types of interest.

(The reason to do the sort first is that repeated sorting of unfiltered data is faster.)

You can do same with the Place column.

I was looking at your requests as specifications. But you’re trying to make certain you have valid basic data, right?

There’s a Gramplet that examines People and Families, looking for those that are missing that kind of data. It focuses around the Home Person. So shifting that focus lets you clean progressively.

Start with the “What’s Next?” dashboard gramplet.


Make certain to try undocking the Gramplet so you can use it in other views. And try out the Gramplet’s Configuration options too.

If you decide that you DO need to use a multi-stage Custom Filter, Here’s a sample that looks for Birth or Death events that are missing the Date and/or Place data:

It is displayed in the FilterParams add-on tool (so you can look at all the interacting filters at once) and uses the “Has Invalid Date” add-on rule.

Or use any combination of these Person filter rules:
