So you’d support a “day” unit of time that has no relation with the times the sun is rising and setting?
if your “day” is exactly a 365th or 366th of a year, you’ll have to work with with the fact a specific hour like 12PM would gradually deviate to be any time from sun’s zenith to the middle of the night.
Days are defined by a different natural cycle, that of the earth’s rotation around its axis. That happens 365.2422 times every time we go around the sun. You can’t just assign the length of a day to something more convenient
A day is defined as a single rotation around earths axis. A year is a single rotation around the sun. The 356.2422 is the result of those two definitions. Earth takes 356.2422 rotations around its axis to rotate around the sun. That is a fact. You could define a unit to be 366th of a rotation around the sun, you could even call it a day, but as a result you lose the reason a day is a useful unit: It’s the time it takes for earth to spin around its axis, a far more useful definition than 366th of a year.
A year is a rotation of seasons. It has nothing to do with the day-night cycle. That should absolutely be separate.
And the 365.2422 isn’t a math error. It’s a mathematic ratio, rotation around the sun / rotation around itself. and it should absolutely be upheld.
The mathematical error os not basing our time counting on that ratio. The number is only 365.2422 because our second, hours, days are too long/short.
We can just decide we want one rotation to be exactly 366 units and then work backwards from there to determine new units.
