hmm, how about 12 months each with 30 days, plus 5 days every year that's not part of any month?

    5 days every year that’s not part of any month

    Those are called intercalary months. They had them in the ancient egyptian calendar (5 every year, 6 in leap years) and were usually used for rest and religious ceremonies.

    Just add a leap month every six years

    You'd have 12 30-day months most years, and an extra in the sixth! While we're at it, we can redefine a week to be six days, so there's a perfectly rounded number of weeks per month/year! Days, hours, minutes and seconds are already fine, but maybe we should also replace units shorter than a second with something more dozenal/hexal(?), too…

    While a novel idea, a leap month would throw the concept seasons and therefore agriculture off significantly. Relatively predictable seasons and being able to track our place in it with calendars was a great help to agrarian communities, helping them know when to plant and harvest most effectively.

    Every 7 or 6 years for a leap week 12 month calendar, it would be four times longer for a leap month, and the formula is a bit too complex for people to do in their heads, but we all refer to computer calendars anyway

    A 364 day calendar with 13 even months, or 12 months alternating between 35 and 28 days or whatever would also let you use the same calendar every year (as opposed to my tea towel that has a calendar that is only useful in leap years that start on a Tuesday — the last was 2008 when it was bought, next is 2036)

    Though it would be too expensive to change the calendar, and a 364 + leap weeks calendar doesn't track the seasons as well as 365 + leap day calendar, I really like the symmetry 454 calendar

    13*28=364 so even 13 months and 28 days doesn't work.

    If we had 28 days in a month then the week needs to be something other than 7 days. Three out of four times February / March fucks me over by having the same weekday/ day of the month.
