Any number for a day, time, and date we happen to come up with is, has been, and always will be COMPLETELY arbitrary... so I don't see that it matters much what system we adopt.
But without time/ date keeping life would be far, far more difficult... so it's something we just can't live without.
Makes sense that it is one of the very first things the ancients actually came up with.
The current system seems to work for most of the folks I can see... so why bother to tinker with something that's functioning just fine?
