> Easter would fall on April 15 every year on Cotsworth's calendar
I don't understand why this would be. Can someone explain?

#22My birthday would always be on a Sunday!
Did you check the day-month of your current birthday, or the day of the year? My birthday is April 8; that's the 98th day of the year (most years), which would be April 14 in the new calendar.

#23When I was at Intel they marked everything in Work Weeks, that was essential for scheduling things like chip fabrication plants. It took a little while to get used to but then it made computing questions of 'when' quite straight forward.
I'm personally in favor of a more structured system like this, my wife on the other hand is viscerally opposed. If that schism is widespread I expect the next calender change to occur when the known world is ruled by an emperor :-)

A very small percentage of the population ever has to write date handling logic. For the rest, things "just work", thanks to those few. Besides, even as a member of that small group, I like the variety of the current calendar, inefficient as it is.
Someone's never written very many sql queries.
I'm pointing at you, tempestn.

Easter is tied to the days of the week, it's always on a Sunday. So it's going to be week-aligned.
This calendar aligns months with weeks. Months are always exactly 4 weeks.

One has to admit that it complicates even trivial communications about days and times. Even questions like "What's the date of friday next week?" can't be quickly answered. Or "Is Nov 12th on the weekend?" I feel these are practical things that _most_ people would _like_ to easily reason about, but can't.
It imperial units for days; or like trying to do math in a numerical system where each significant digit has a different random radix. Does it have variety? Yes... Is even remotely fun to do anything practical with? No.

#28This would complicate anything that is paid for monthly, including but not limited to: employee salaries, rent/mortgage, subscriptions, utilities, etc. Do we just ignore Sol for those purposes or roll it into another month? Having your birthday perpetually on a wednesday would also not be so much fun. Perhaps "year day" could shift every year forward by 1 week day - year day could be Monday and then Jan 1 of the next…
Don't some companies already run salary in thirteen four week periods? I've worked at at least one that did.

#29This seems to be slightly inferior to the Pax calendar[1].
The Pax calendar has another very cool property, which is that the weekdays are always in sync with Gregorian calendar. This is done by carrying over leapdays until you have one full week accumulated, which is then inserted as a leapweek, in the same way we insert leapdays in the Gregorian calendar.

#30Fun fact:
The arabic calendar which is based on Moon movements used to have an extra month every four(?) years to adjust the season changes. It was called Nasi' month. But after a Quran Sura published that prohibited this month Arabic calendar lost it's accuracy for seasons.[1]
The Iranian Calendar that is based on sun movements was safe from this Sura because it didn't have an extra month but an extra day each five years.[2]
