This kind of sounds like "I choose semantic versioning but actually I didn't really need semantic versions, so now I just have a dated build number" It's fine, but its not very useful in many different kind of situations. Like for instance managing firmware versions where you have a version 5 which is the last version compatible with a certain level of hardware and you need to hot fix it, while the most "modern" version is version 9. But if you just keep releasing something like a website, then yeah, all you need is a build number, the date might be helpful, but most likely you don't care too much about that either.
