The 365.2422 days per celestial year is a math error we can fix.
We need to adjust the length of days and seconds but we can get rid of it completely if we wanted to.
It’s not like noon means the maximum of the suns arc or sunset and sunrise don’t already shift throughout the year.
The only thing that stops it is the momentum of a human measurement error.
If we use 366 we just get slightly shorter days by about 3 minutes. All of these time measurements are more arbitrary than feet and inches. Science back filled the bullshit with physical constants and there is no reason we cannot tie a proper system into alternative physics constants.










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.
