I've got a bot that scrapes release groups on MusicBrainz to get album release dates, but it doesn't always work right. As far as I can tell, release groups don't really have "release dates", only releases do. So I'm using the heuristic that my bot should use the earliest date of an official release in a release group.

As an example, my bot flagged today as the release anniversary of *...I Care Because You Do* (https://musicbrainz.org/release-group/79c6d3be-251c-3644-b07e-09d738e15a84) because the german release date is marked as 1995-04-01, but per wikipedia, the album was released on 24 April 1995. 

I'm guessing that's a mistake in the release. I'm not sure where I'd look to confirm the german release date to make an edit to the page. Does MusicBrainz automatically fill in the date as the first of a given month if a user only provides a year and month but no date? Is that why the date might be marked as 04-01?

Is there a better way to see an album's "release date" than what I'm doing now? (Pulling the earlier date of an official release?)
