The following line is failing because there is a project without submission_datetime and editor_assignment_datetime.

days = [d.days for d in y_durations if d.days >= 0]

The culprit is a legacy project that at some point was switched to non-legacy:

projects = PublishedProject.objects.filter(is_legacy=False)

p = projects.filter(publish_datetime__year = 2010)
<QuerySet [<PublishedProject: CHB-MIT Scalp EEG Database v1.0.0>]>

I think we/I probably switched the legacy status so that the landing page would display citations (p.is_legacy is set to false).
