A question from a (beginning) Danish language learner

Finally a context for a dad joke, I've had laying around! What's sitting on the bottom of a bucket going "dav dav dav"? A spandauer

Can't recall having heard "Dav" used as a greeting for ages. I'm 40+ and been living in Copenhagen most of my life. I've heard "Godaw" once in a blue moon, when talking to people from Jutland

We use 'dav' in my family and I sometimes use it outside of that context, but I don't think I ever hear other people use it.

I think a lot of people answering here have not been in Jylland since it's quite common in some areas and circles. I feel like I've heard it myself quite a lot, so much so I do it myself now even after I moved to kbh.2 years ago.

I've heard people use it before but it's very rare. To the point where I'd say using it is more of a personal quirk rather than any group preference.

It's a casual greeting, usually only used among friends I'd say. It's a shortened version of "Goddag".

I've grown up in a rural area, and while I associate dav/davs with old farmers or workers, I rarely hear them use it nowadays.

I occasionally use "davs" semi-ironically but it is definitely not the most common greeting. It's probably not a greeting you should use the first time you meet someone, or at a job interview, but it is fine (albeit a bit atypical) for greeting friends. Hej or hey are more common, and as a bonus, also much easier to pronounce for the average English speaker.

It sounds like the usage of "Dav" in Danmark might be similar to the usage of "Howdy" here in the USA.

I think it might be more about the circles you're in. I personally haven't heard or used it while living in various places in Jutland, albeit urban areas.
