[Pitch] Extending Date with methods to get specific new dates

… Unless we have some sort of system of shared time instants to refer to.

This isn’t mitigated by the “It’s just a label” theory presented upthread.

To be clear, we're not talking about "dates divorced from a concept of time", we're talking about "dates without specifying time of day". i.e., the same concept of loose equatability you're talking about.
