Ask HN: Why not release software versions with yyyy.mm.dd.hh?

We see very often on HN that we're discussing about an interesting software package, and it is left to the readers to dig up the relevant Github or other repositories to find out if the software is maintained or not, and when was the last time the software was released.

Is there a reason to use something like semantic versioning instead of just dates?

Example - redis.2017.10.27.11 is easy on the eyes as a current package...
