Searching obs with no date


I want to search observations that don’t have date value.
I tried with different combinations through url, but I can’t find a way.

Can someone help?

I found a way :)

Not quite, since that will include observations that have dates but are casual for other reasons, such as:

  • observation is flagged
  • photo is flagged as copyright infringement
  • observation taxon is human
  • communtiy taxon is marked as “unable to be improved”, but the current taxon rank is > family

Why are you searching out these observations? I’m just curious.

I noticed that my observation doesn’t have time because of some app bug, and then I was looking at some other causal obs from Croatia, and I noticed that there are lots of this cases so I wanted to search them through url bar.

If there is a way to do this, I will be easier to “improve” causal obs by asking observers to add date.
For now it is to hard to find this cases among all other casual obs.


Same here - these are some of the easiest ‘casual’ observations to uplift to Research Grade as the user has generally just not realised that the observation date didn’t sync. I found quite a lot of these from India.

Either of the following brings up the same set of casual observations, with bad dates at the front of the line, but there is still a (bad) date displaying, not completely blank:

Both of these were created through the regular Filters dialog.

Wow, that’s the first time I’ve seen bad dates! entertained by the comments on the first one.
