That doesn’t answer how you would get everyone to go along with it. Every program with dates needs to be rewritten. I once again remind you the difficulty in getting rid of Daylight Savings time which requires effort on people to maintain and causes documented problems every year.
You also haven’t explained why this would be worth the hassle of doing so.
I did not say it would be difficult to develop a better system, I said it would be incredibly difficult to implement a better system.
