For most proposals like this, new years day and leap day wouldn’t have a day of the week. And therefore the calendar wouldn’t change from year to year.
I think your code is fine. The Gregorian Calendar actually runs on a 400-year cycle (i.e. the pattern caused by 7-day weeks, variable-length months and leap years repeats every 400 years) so if you re-ran the code against a 400-year period you’d get the correct ratios.
I’m a nerd so I had to write code to check this out.

So from 1/1/1500 until 12/31/2023:
Weekday counts: Monday: 898 Tuesday: 897 Wednesday: 901 Thursday: 896 Friday: 901 Saturday: 896 Sunday: 899
No idea why, and other than a tie with Wednesday, this is indeed true. Well if my code is correct.
Depends on the year you start, it is thrown off by leap years.

I was just talking about why there have been more fridays the 13ths since 1500.
My eyes see mixed-endian! I want them to unsee it!
Decide already whether you want 2023.12.31 or 31.12.2023.
