Can we search for list of issues for which a specific label got added/updated between a time period?

We as QA are setting a label called "re-open" when we re-open the issues. Once the testing is done. We want the list of issues for which the label i"re-open" is updated or added in between a time period (in this case our testing time period).

I don’t think you can do this with JQL for labels. With that said, I assume you have a transition to “reopen” an issue? You could consider constructing a JQL of when issues were reopened. Basically you look for issues that were closed and now open. Another consideration is to actually have a “reopened” status which gives you a bit more flexibility to analyze these issues.
