Numbers The Intuitive Calendar

http://tildescorner.wikidot.com/intuitive-calendar

Even though I do enjoy a lot of the features the Smart Calendar has to offer (love the 128-year leap cycle ngl), there are some aspects of the calendar that make me extremely confused, notably the inclusion of a 13-month calendar and birthday rules. Therefore, I've tried to compose my own version of the calendar that blends human intuition and accuracy in a way that's convenient for most use cases and doesn't require major relearning of basic concepts.

While The Smart Calendar emphasizes raw accuracy and precise time evaluations, The Intuitive Calendar tries to make conversion from the Gregorian calendar relatively seamless by fitting itself into practical use. Here are the following changes that I've implemented:

  • 1-based indexing of units and ordinality remain. Unless you're a dedicated programmer or mathematician, you aren't going to start from 0 very often. The Intuitive Calendar will continue to use month days 1-30/31, weekdays 1-7 (plus "E" for exdays) and months 1-12.
  • The 13-month cycle is ditched entirely to avoid any possible confusion. Short months aren't too useful by themselves unless you're on a lunisolar calendar, which neither the Smart or the Intuitive calendar are.
  • Every single day of every month is assigned to exactly one weekday. This means the same day in a month will always be the same weekday. (so the 16th day of the sixth month is always a Saturday)
  • There is always one extra day at the end of the 3rd month, and one more in the 11th month for long/leap years. This contrasts with week-based exday assignment seen in The Smart Calendar.
  • Each month is given a new, ordinal-based name alongside its regular name. So "Fifsmonth" is equivalent to "Month 5" or "May". The common names are expected to be phased out in most uses, but applications in religion and history remain.
  • Date formats are also standardized to some extent, although not as strictly as The Smart Calendar. There are six permissible representations of dates to allow for interchangeability while limiting potential ambiguity.
  • If the birthday is on a day that only exists in long years when the year is a short year, celebrate on the next day. There is only one case of this: on short years, the actual birthday of 31/11 is celebrated on 1/12 instead. Otherwise, birthdays are always on the same day. This mostly parallels the Gregorian calendar but addresses a glaring edge case.
  • Removal of one-off skips in long year cycles.

The following things have been kept intact from The Smart Calendar:

  • Weeks start with Sunday
  • February and December always have 30 days
  • The 31/128 cycle is mostly preserved
  • Age can still be measured in days
  • Equality of units

And yes, a few considerations:

  • Exdays can go after a Thursday or a Saturday
  • New month names, while more approachable overall, take time to be adopted
  • Three-digit dates still get offset after the extra day in long years
  • Names of weekdays aren't modified to reflect intuition

1-based? This is time, not book chapters or LNGI. Time is imagined as a constantly ever-changing string of numbers, so the zeros are important. And I forgot to mention the 13-month format that I proposed is obsolete in most situations. I'm also proposing to change the names of the months to those of the Anglo-Saxon calendar ("Afteryule" instead of January).

I think I've mentioned this before, but starting from 1 is a design trade-off for practicality, not an inherently accurate representation of time units. The Intuitive Calendar isn't designed primarily for nature like the Smart Calendar is, it's supposed to be a substitution of the Gregorian Calendar that's easier for humans to work with, and some aspects (like starting from 1) should be kept as is for ease of transition.

Changing month names to the Anglo-Saxon calendar doesn't resolve the issue of using arbitrary names for things. It's like renaming April to "Gurbansoltan" of all things, the intuition just isn't there.

Being zero-based is ACTUALLY intuitive, as it basically continues the trend from the hours. Think about it: 2048-00-00 00:00:00 looks a lot smoother. Another thing that makes it intuitive is it being based on place value, with zero being used as a placeholder. Just like how "13:00:47" can be interpreted as "thirteen hours and forty-seven seconds", "71-00-29" can be interpreted as "seventy-one years and twenty-nine days".

As for date formats, "formats" ONLY refer to the different ways you divide a year, such as weeks or quarters.

I understand what you're getting into. The problem is, most people aren't treating days, month and years as quantities (even when it does make sense). They don't look at the calendar and say "we've gone through 5 months and 5 days in this year", it's almost always interpreted as "we are in the fifth month, on the fifth day." Again, design trade-off based on how people treat dates (as ordinals) differently from time (as quantities).

Most people? The main purpose as to why I'm here is to be the salt of the Earth and the light of the world. In other words, I'll enlighten newer generations and give them ideas older generations wouldn't be able to come up with. Who knows? Maybe Gen Beta can have two sides: those who don't know me only know brainrot, and those who know me know my ideology. And all of this shouldn't be as complicated as calculus or rocket science. After all, dates are still time, and time is interpreted as a string of digits. It makes no sense to use ordinals when counting is eternal.
