       | I don't think this reformed calendar goes far enough. Many of our
       | services are billed monthly - Internet, phone, electricity,
       | property tax, etc. I don't know if the pax week would be
       | considered its own super-short month or fused into another month,
       | but it massively complicates financial calculations and issues of
       | fairness.
       | 
       | Other people have pointed out issues like with 13 months, you
       | can't divide the year into quarters.

       | 
       | For anyone thinking that will be a pain to code, side benefit,
       | it'll hasten the adoption of sum types.

       | I recently ended up in a wikipedia rathole looking at various
       | alternative calendar systems, at least in part to be able to give
       | a true but unintelligible answer to the question of when my
       | birthday is. Among the oddballs were the Discordian calendar
       | which divides the year into five seasons of 73 days each with
       | 5-day weeks and the Pataphysical calendar which has 13 months
       | each of 29 days, but for most months, the 29th day is imaginary.

       | Pretty unpleasant to have an extra week once in a while, IMO.
       | Seems this calendar would lead to confusing seasonal drift in
       | more stable (pre-industrial) climate, but I guess there's no
       | seasonal predictability going forward .
       | 
       | As a fun thought experiment, I once devised my own Equal
       | Terrestrial Calendar, intended to be both predictable and
       | _actually_ secular.
       | 
       | - Weeks are 5 days long.
       | 
       | - Months are 6 weeks long (exactly).
       | 
       | - Thus, a month is 30 days, and as close as possible to an
       | average lunar month.
       | 
       | - Every week/month/year begins on the same day of the week
       | 
       | - Work weeks are 3 days long.
       | 
       | - 3 intercalary holidays at the winter solstice, and 2
       | intercalary holidays at the summer solstice (make it 3 every leap
       | year)
       | 
       | - 30 days/month * 12 months + 5.25 days (intercalary) = 365.25,
       | but in a fairly even spread
       | 
       | Not possible for a calendar to be perfect, but I'd really enjoy
       | living in this world.

         | What if instead we were to go with non-24-hour days? We could
         | fix even more problems with such a system, like:
         | 
         | * Days starting at the same hour:minute all the time
         | 
         | * The current impossibility of a decimal clock. We're
         | constantly told how using base-10 makes math so much easier,
         | who wouldn't want a day being 10 hours long and a week 10 days
         | long? If the answer is 168, you've screwed up somewhere
         | 
         | * The conceit that ancient deities like Apollo and Ra are so
         | important that even after we've abandoned those religions, we
         | must continue to allow our calendars revolve around their
         | golden chariots. I say "no more!", we will spurn the
         | astronomical bodies as well
         | 
         | * The relegation of agriculture to the primitive past, where it
         | belongs. I only eat Hot Pockets anyway. The chicken milkers and
         | tomato tree people can go live in yurts or something if they
         | believe caveman calendars are important
         | 
         | * The ability to insert special 5-minute days into the calendar
         | in emergencies, like when I have a new game on pre-order that
         | is scheduled to come out in 60 days' time. We could easily
         | reduce that to an effective 3 hours or so

           | Sounds fun. But the day is evenly divided already, so there's
           | less pressure to change it.

       | 
       | For most of human history, we didn't need a standardized
       | calendar, you just needed to agree with people that you
       | interacted with. Religion pushed most of the standardization and
       | later reinforced during the Industrial Revolution--helped along
       | by colonialism.
       | 
       | Now that we are a globalized society, it would require parties
       | from every nation and every industry to agree to the change and
       | coordinate a simultaneous migration. Given we can't get close to
       | that level of cooperation when faced with potentially existential
       | crises, it's doubtful we could do it because it's a "better"
       | system than the current one.
       | 
       | I'd love to be proven wrong though!

       | One day, I hope to live in a world where I get to use this
       | calendar and the average response isn't for people to look at me
       | funny...
       | 
       | For anyone looking for a tl;dr, Symmetry454...
       | 
       | - is perpetual; one printed calendar will work, more or less,
       | indefinitely
       | 
       | - preserves the 7-day sabbatical week cycle (no intercalary days
       | like IFC)
       | 
       | - simplifies the leap rule to a formula which should work for a
       | very long time (at least a few millenia from now)
       | 
       | - preserves 3 months in a quarter, and 4 equal quarters making up
       | a year
       | 
       | - results in every week, month, quarter, year, etc. beginning on
       | a Monday and ending on a Sunday; this also means knowing just the
       | day number tells you exactly what day-of-week it is
       | 
       | - ensures all months now consist of a predictable, whole-number
       | of weeks
       | 
       | ... it's just... so much better...
       | 
       | All the best,

         | What about this idea for a calendar: every year is 1 month,
         | every month is 1 week, and every week is 1 day?
         | 
         | - Every year and month starts on a Monday
         | 
         | - No leap days needed at all
         | 
         | - You can use the same calendar every year (better yet, you
         | might already have a blank piece of paper you can use)
         | 
         | - Every day is your birthday

           |
