- see, the language is not that simple as you think, it has this complexity you haven't thought of, so it fails
- the language is as simple as you think, but no one would ever speak like that, the real world is more complex, so it fails
Sometimes those two get mixed up in the same sentence.
- A leap week is worse than a leap year. 7 days of birthdays that just don’t exist most years.
- No variety in day of week for your birthday. I know it’s just a cultural thing, but always celebrating a birthday on say a Tuesday sounds depressing to me.
Worldwide flag days are fatal to progress.
I suppose in-grained traditions that are so hard to change (birthdays, memorials, etc.) make this nigh impossible.
Any calendar will need need to ensure that those relationships can be represented with only minor but consistent variations, e.g. leap years). Weeks largly stem from there being roughly 28 days in a lunar month.
If we're freeing ourselves from any relation to Earth's physical progression through space, e.g. 24 hr day, ~28 day solar month, or 365¼ day year, there would need to be a compelling reason, e.g. being a largely and widespread spacefaring civilization.
The obvious conclusion is that they would have only 1 day off.
I believe that the closest thing that existed was French Republican calendar [1], accompanied by decimal time [2]. The Swatch Internet Time [3] which uses decimal minute at its base is also worth mentioning - it's almost forgotten nowadays.

And I say that as a purist and nitpicker who loves everything being perfect and organized.
Sounds similar, and IMHO a bit better, because every month is the same and has only one leap day, instead of a whole leap week.
This sounds great except the fact it would be a complete nightmare for developers the world over.
