After investigation, it turned out I had to load tzinfo in to the database, as described at https://docs.djangoproject.com/en/1.6/ref/models/querysets/#database-time-zone-definitions. Although the release notes mention this is required for the new QuerySet.datetimes() functionality, there was nothing mentioning it was required for using week_day lookups. As this could break previously working projects with Django 1.5, it should probably be made clear in the release notes and queryset documentation."
