I feel we should do like that with 12 30 month days consisting of five 6 day weeks so a particular day of the month is always the same day of the week. then the 5 extra days exist outside has holidays. the equinexes and solcti along with an extra just after winter solcti for new years
This works if there are only 364 days in the year. Otherwise, one month would have to be 29 days long.
Just have that day exist outside the 13 month system, make it a holiday that’s sometimes 2 days long on leap years
