theAbysmal Calendar .is a proposed calendar system with several functions: it provides a numeric global calendar system to mediate between other calendar systems; it organizes the year in a variety of regular measures; it is synchronized with the natural time as defined by the day, the moon, the seasons.

TheAbysmalYear

Cardinal Numbering[]

Every measure of theAbysmal Calendar begins with 0, and counts time only after it has completely elapsed. This is an extension of the way we count seconds, minutes, hours to measures of the days, weeks, months, years, and so on.

Epoch & Eras[]

theAbysmal Epoch began with the New Moon prior to the Northern Solstice in 1492 CE - May 26th on the Julian Calendar.

theAbysmal Calendar measures two eras, a short one of 260 years and a long one of 5,200 years. The short eras to this point are as follows:

Era 0 began May 26th, 1492 CE (Julian)

Era 1 began Jun 11th, 1752 CE (Gregorian)

Era 2 began Jun 19th, 2012 CE (Gregorian)

Observational Lunar Calendar[]

This function of the calendar counts every second, day, week, moon, and year without further correlating any of them. This is a linear count and provides a means of translating dates between solar and lunar calendars. While these numbers ultimately begin with the Epoch, following by Era is more pragmatic.

Era 2 began with:

  • second 00 = midnight UTC Jun 19th 2012 CE at 180 degrees longitude (IDL)
  • Day 0 = Jun 19th 2012 CE
  • Week 0 = Friday, Jun 22nd 2012 CE
  • Lunar Month 0 = Jun 19th to Jul 18th 2012 CE
  • Year 0 = Jun 19th 2012 to Jun 7th 2013 CE

13~Month Calendar[]

theAbysmal Calendar has a rules-based, fixed, annual solar calendar, which divides the year into 13 months with 1 day outside of any month on Dec 21st at the Southern Solstice. This creates a symmetrical structure aligned with the seasons, as well as harmonizing the 7-day week with the month, the quarter, the semester, and the year.

As the calendar is strictly numeric, anyone is free to name the days, weeks, months, years, etc. however they choose.

Structure of the Year[]

365 = 364 + 1 = 7 x 52 + 1 = 7 x 4 x 13 + 1

Defining the year in this manner allows us to make regular divisions.

  • 52 weeks + 1 day = 1 year
  • 26 weeks = 1 semester
  • 13 weeks = 1 quarter
  • 4 weeks = 1 month
  • 2 weeks = 1 fortnight

Each of these measures fits evenly into the year, + 1 day.

This also makes each of these a regular measure, which is a significant drawback of the Gregorian.

  • 1 week = 7 days
  • 1 fortnight = 14 days
  • 1 month = 28 days (4 weeks)
  • 1 quarter = 91 days (13 weeks)
  • 1 semester = 182 days (26 weeks)
  • 1 year = 364 days (52 weeks) + 1 day

Days of the Week[]

theAbysmal Calendar has no authority over the Weekdays however, these two daykeeping systems synchronize together with an underlying 28-year pattern.

theAbysmal New Year 0 (Dec 21 2012) fell on a Friday, making Month 0 Day 0 a Saturday. For the duration of year 0, every fortnight, month, quarter, and both semesters began on Saturday. Year 1 began on Sunday, and so every fortnight, month, quarter, semester began on Sunday, and so on. Year 2 began on Monday. The following year, being a leap year, is divided in two halves: the first half began on Tuesday, the second half on Wednesday. Year 4 began on Thursday, and so on. This creates a 28-year cycle.

Leap Year Rule[]

365 + 1/4 - 1/128

A Leap Day is observed on Jun 21 in a year following Feb 29 (Gregorian). There is an exception every 128 years where no Leap Day is observed, however the timing for this hasn't been decided. This will put theAbysmal Calendar and the Gregorian out of synch in 2100 CE.

An alternative is to synchronize with the Persian calendar rather than the Gregorian. Every quarter begins on a Solstice or Equinox, and their leap year rule is equivalent to theAbysmal's, however, it's smoother.

365 + 8/33

For the moment, this is undefined. The Leap Day and Leap Year are features that define the Fixed Year, which remains aligned with the Seasons. The Wandering Year (also called a vague solar year) and Scattering Years don't observe a leap year.

Notation[]

Numbering begins with 0, largest to smallest left to right, and punctuates notation as follows:

  • dates are separated by tilde (~)
  • times are separated by colon (:)
  • anything less than a second is a decimal (.)

Example:

4~7~0 22:34:59.22

Year 4 Month 7 Day 0 10:34PM and 59.22 seconds.

Other Calendars[]

The annual calendars are organized by regular weeks, months, longer divisions, as well as the type of year.

Type of Year[]

theAbysmal follows several types of calendar year: the lunar year detailed above, a Fixed Year, a Wandering Year, and various Scattering Years. The Fixed Year is synchronized with the seasons by the observation of a leap day, the other two do not. As such, the Wandering and Scattering new year dates shift at various rates.

Fixed Year[]

theAbysmal Calendar's fixed year inserts a leap day on Jun 21 in a year following Feb 29 on the Gregorian. This makes the New Year for odd-numbered years (i.e. 365, 363+2, and 361+4 days) Jun 22 and the New Year for even-numbered years (i.e. 364+1, 360+5 days) Dec 21.

Wandering Year[]

The Wandering Year is known as a vague solar year, in that it is a continuous cycle of 365 days without a leap day. The arrangement of days of the year into weeks and months is the same for both Fixed and Wandering calendars, however, their new year dates fall one day apart every 4 years.

Both the Fixed and Wandering calendars were aligned from Jun 22 2020 until Jun 20 2024.

Scattering Year[]

The various Scattering Years are cycles longer or shorter than 365 days. The 3 Scattering Years are intended to harmonize all of theAbysmal Calendar's market weeks (see below).

Market Weeks[]

A market week refers to a week of duration from 3 to 13 days. By skipping 1 to 5 days, a great number of market weeks fit the 365-day year.

365 = 5-day week x 73

364 = 4-day x 91, 7-day x 52, 13-day x 28

363 = 3-day x 121, 11-day x 33

360 = 3-day x 120, 4-day x 90, 5-day x 72, 6-day x 60, 8-day x 45, 9-day x 40, 10-day x 36, 12-day x 30

Note: the leap day is a blank day that occurs between weeks (imagine an entire day inserted between Saturday and Sunday). Skip days also fall between weeks within the 365-day year. The Wandering 365 and Scattering Years produce an uninterrupted stream of market weeks.

Market Week Harmonic[]

Beginning with Era 2 Day 0 (Jun 19 2012), the uninterrupted cycle of market weeks as well as the Scattering Years began.

360,360 days = 23 x 32 x 5 x 7 x 11 x 13

This harmonic number accounts for all the market weeks from 3 to 13 days long. They will begin on the same day again Feb 5, 2999.

The 3 Scattering Calendars map these market weeks.

360,360 = 360 x 1001 = 364 x 990 = 385 x 936

Regular Months[]

theAbysmal Calendar developed a simple formula for creating months out of market weeks:

365 days = days/week x 3-5 weeks/month x months/year + extra days

364 = 7 days x 4 weeks x 13 months = 13 days x 4 weeks x 7 months

363 = 11 days x 3 weeks x 11 months

361 = 19 days x 19 months

360 = 5 days x 3 weeks x 24 months = 5 days x 4 weeks x 18 months

360 = 6 days x 3 weeks x 20 months = 6 days x 4 weeks x 15 months = 6 days x 5 weeks x 12 months

360 = 8 days x 3 weeks x 15 months = 8 days x 5 weeks x 9 months

360 = 9 days x 4 weeks x 10 months = 9 days x 5 weeks x 8 months

360 = 10 days x 3 weeks x 12 months = 10 days x 4 weeks x 9 months

360 = 12 days x 3 weeks x 10 months = 12 days x 5 weeks x 6 months

The difference between the Fixed, Wandering, and Scattering 364- and 360-day calendars is apparent in whether they observe leap and skip days or not., as well as the dates they began.

Multi-Year Measures[]

It's also possible to create weeks and months that fit better into multiple years. The most compelling example of this is the two-year, 27-month calendar as in Trical.

729 + 1 = 365 x 2

729 = 272 = 93 = 36

This creates a more comprehensive system for the 3- and 9-day weeks, and also makes a 27-day month possible. There are many other possibilities for 3-, 4-, and 5-year systems.

Fixed Year 364+1-day and 360+5-day calendars began Dec 21 2012.

Wandering Year 360+5-day calendar began Jun 24 2012.
