Lunisolar Calendar Puns

Just out of curiosity, this year the pre Christian Nordic lunisolar calendar marks Jan. 17th as the night of yule. Do y'all think that's too late to celebrate ? I've done it before and when I wait till the more accurate timing in the heathen calendar, here where I live in California it just feels like winter is already over even though it's still cold, all the seasonal decorations are gone and it just doesn't feel right. So this year we celebrated this past weekend on the full moon, which even though it's closer to the solstice it feels better. I use to be hard on myself for striving for historical accuracy, and then I just realized it's not about that, it's about getting together in general around these seasonal shifts and celebrating with friends that makes it so special. Just my take on things

toki!! sorry for the really nasa title. i promise itll make sense by the end.

i really love the toki pona lunisolar calendar created by /u/pisceyo . (if you would like to see a working rendition of that calendar, o lukin e ni tan /u/just-a-melon ). one feature of the lunisolar calendar is that its months (or moons, as i will use commonly thruout this post) lack names. here is my sugestion for a potential month naming system.

why might month names benefit the lunisolar calendar?

while tying the moon names to local seasons can be good for personal or local use, it is prone to issues in an online setting. all over the world, the local seasons vary alot. in the southern hemisphere, many places have 4 seasons but in an opposite arrangement to temperate northern hemisphere countries. some places have more than 4 seasons. some places only have 2 seasons. also, if you have 6 or 8 months of one season, thats going to be hard to talk about in a language where the numbers bigger than 2 are deliberately difficult to say.

it would be simpler if the moons of the toki pona lunisolar calendar had names that everyone could use, no matter their local seasons. these names would have to be based on something other than seasons? in many cultures, months are named after mythological figures.

i have always been struck by how poetically beautiful the big bang and the evolution of life on earth is. to me, its like a creation myth. so i wrote a creation story in toki pona inspired by evolution. it is called toki tan and it is in the form of poetry. it is at the end of this post.

so what would be the month names?

i picked toki pona words as the month names. this means that this naming system requires neither new words, nor loan words to operate. the month names are:

mun Wan, mun Kon, mun Seli, mun Ma, mun Telo, mun Mama, mun Kasi, mun Pipi, mun Kala, mun Akesi, mun Waso, mun Soweli.

the intercalary month is still called "mun Namako". moon names would be capitalized in writing to disambiguate them from normal toki pona words, and because they are technically acting as proper names.

the names are symbolic of important moments for the evolution of life on earth, arranged roughly in chronological order (i make no claims of their exactness. the precise timing of evolution is complicated to measu

As some quick background, I was inspired by the toki pona calendar here: https://www.reddit.com/r/tokipona/comments/dr378j/lunisolar_calendar_for_toki_pona_done/

and, while not directly relevant, the mun names here: https://www.reddit.com/r/tokipona/comments/oikpr8/toki_tan_a_creation_story_in_toki_pona_inspired/

This calendar is fantastic. It feels very toki pona to me. I'd like to add a clock to it, one that has similar stylistic goals. Even if you do not need to specify the exact day when you have the phases of the moon, you may wish to specify approximately the *time* of day. (Also, I'm making a commandline app for the calendar so it can sit on my desktop and look pretty, but I want it to update more often.) And so I present my toki pona clock!

This system doesn't have "hours" per se, and definitely doesn't have minutes or seconds. But the day can be split up in multiple ways depending on need, much like how the phases of the moon can be described several ways.

I split the full day into 6; three suno segments based on the movement of the sun, and three pimeja segments based on the cover of night (literally. For the naming system I imagined the night sky as a cover that is drawn over the world. By what or whom? We may never know!) I don't follow the moon here as it can sometimes be up during the day and down at night, and also because people already use "tenpo suno" and "tenpo pimeja". This gives (in order):

• pimeja pana
• pimeja len
• pimeja weka
• suno kama
• suno awen
• suno tawa

Since days start at sunset (see the calendar linked above), I've decided that the end of "tenpo pimeja" and start of "tenpo suno" will be at sunrise. This means these "halves" will be different sizes at different times of the year, and so will their segments. I think this meshes well with toki pona's lack of precision. (It also means it's less useful in the arctic and antarctic circles, but they do strange things with time anyway.)

You can further specify time within these segments if required. For example "open pi suno kama" may mean right at or immediately after sunrise. "pini pi suno kama" may mean just as the sun is getting to what feels like the "awen" part of the day. "meso pi pimeja len" may be roughly midnight. Much like with the calendar,

Salaam, all! It's 2021 on the Gregorian calendar. And If you follow the strictly Hijri lunar calendar, Ramadan will commence around the 12th of April. But If you follow the Hijri lunisolar calendar, Ramadan will commence around the 8th of September. So, which date will you observe and why? Personally, I've been observing Ramadan on the Hijri lunisolar calendar for the last couple of decades because I believe the traditional interpretation of Quran 9:36-37 is dubious. But for those of us who follow the Hijri lunisolar calendar, and for those who don't follow it, there's not a lot of info on the Hijri lunisolar calendar. So, I created these calendars for the years 2021 through 2025 and a historical timeline with Common Era (CE) and Hegira Era (BH & AH) years for those who are interested. Coincidentally, It's African American History Month here in the US and there's more dates on the timeline related to Africa and people of African descent than you'd usually find on a timeline of Islamic history.

Okay, here is my calendar, use ad urbe condita, at least until something happen like a t'osuua invasion or anything.

All month have between 30 to 29 days,

The New Year start with the solstice of summer. And like is show it, the month is divided between two moments, the nights of darkness and nights of light, or new moon and full moon, those period are composed by weeks of 5 days, and the day go sunset to sunset, NOT IN DAWN TO DAWN OR MIDNIGHT TO MIDNIGHT, IN SUNSET TO SUNSET.

A new month is added before the first month in the second year, and other month come after the six month in the third year, in intervals of five years. Those extra months are of 30 days in total, with his own 15 Nights of Darkness and 15 Days of Light of course.

To my, this is the basic Trasgian (and relateds) calendar at least.

PD: I made a mistake, I made this in base to a irl calendar, and I bad interpreted a sentence about it, so I changed a paragraph.

First, some background information: The Suri are a pastoralist people living in a Sahel-like region on a fictional planet called Oberus. The Suri have a well-known history of astronomy and have knowledge that the planet makes a full rotation every 476.2 days, and the moon makes a rotation every 32 days.

During the Old Suri Kingdom Era, Suri astronomers developed a calendar system to help aid the tribesmen with the hunting season. Because the Suri live in an area without much variation in photoperiod, the calendar was intended to separate the wet and dry season into two parts, and allow for more accurate timekeeping. This system was based on the number 8 (The Suri numbering system is base-8) and the rotation around the sun. The Old Suri Calendar was composed of eight months of alternating 59 and 60 days.

The months of the Old Suri Calendar were:

Each of these months simply come from the Suri number 1-8 + -kō, originally the word for "month", but now has shifted to mean sun.

Every five years an extra day is added to the final month, Magō, in order to allow the calendar to stay consistent with the planet's rotations. This day was considered a very fortunate day and was a day of great celebration. Even in the new calendar system, the final day of Magō is one of the most desirable days to be born.

Eventually, in the Classical Period, Suri astronomers wanted to make a calendar that more accurately followed the rotation of the moon. So, a new calendar, incorporating the old was made. This calendar was split into 14 months of 34 days each, closely mirroring the moon's rotation. Six new months were included. These were:

The new order of months was: Hyōkō, Irekō, Kenkō, Sōkō, Jamekō, Rinakō, Yōkō, Obekō, Tōkō, Korokō, Sojagō, Tekkō, Kukō, and finally Magō.

Please Let me know what you think!

toki, jan ale o. It's me again! Yes, the podcast guy. The toki kala podcast will hopefully be airing later on today, however this post is about something else entirely! Im going to break this post into sections so you can skip over ones if you already know/dont want to read it all.

ABOUT CALENDARS Toki Pona has a lot of semantic basis in hunter-gatherer societies, so theres words like alasa but no root word for say, electricity. This also carries over to time. People, because we all live in the 21st century, live in worlds that have a lot of time measurement in them. Hours, minutes, seconds, milliseconds. We have a calendar that bases the year on the earth's orbit around the sun, and breaks that up into some months and days for us. The Gregorian calendar.

However, the Gregorian calendar is not the only one in existence. There are many calendars from essentially every culture, sometimes based on the moon (such as the Islamic calendar), and sometimes based on the sun (like our calendar). However, there are also these little things called lunisolar calendars, a truly magical creation, that track both the phases of the moon AND keep everything within the general realm of the solar year and the seasons.* The chinese, buddhist, vietnamese, hindu, babylonian, and hebrew calendars (to name a select few) are some examples of these. Every calendar system requires calculation, and theres no one way to do each.

So, where and how does this all tie into toki pona?

CURRENT TOKI PONA TIME Well, Toki Pona is a language used by humans in the 21st century, all of which have internet access. Thus, we are affected by the passing of the sun and moon in the sky (also affects how we sleep, what we do, what we see) as well as our position in the year based on a calendar, typically the Gregorian calendar. The language reflects this.

Problem is (back to the beginning of the post): Toki Pona wasn't made with these things in mind. In fact, it was made with them, to some degree, intentionally out of mind. A solar calendar is more about the day of the year and whatnot, cuz the sun is a much LONGER cycle to measure, but toki pona does NOT fit this system well. You tell me its "December 27, 2019" without using nimi sin and/or weird number systems that break the intentional lack of one. So we get things like, "tenpo mun" to mean 'month' and "tenpo esun" for week [not the only things youll see but (most) common ones]. But... the months of a solar calendar arent

Nevermind I just realized I made a stupid mistake

I was working on a calendar for a future earth that has a moon orbit period of 4.63914352 days, while there is the regular Earth orbit period. Days are just as long, and the only thing changed is that the moon is closer. I'm not very good at math, but I have all the other calculations and data for the calendar itself, but I'm struggling to have it not go off track of regular Earth, I'm not sure when to add a leap month. I have looked up multiple guides to help, but I'm still lost. Any help would be appreciated, thank you!

Data:
Moon orbital period- 4.63914352 days
Earth orbital period- 365.256 days
Length of day- 23.9333 hours
Number of Months- 78.73349864 months

I’ve been attempting to construct a more formalized modern version of the Germanic lunisolar calendar, but I haven’t been able to find anything consistent about with lunar phase begins a lunar month. I’ve found mentions of Scandinavians marking the first full moon after the winter solstice as the beginning of the year, and Bede mentions that the Anglo-Saxons considered the full moon of October to be the beginning of winter, but would that full moon have been in the middle, beginning or end of that lunar month?

Just figuring that today is CNY, so it's somewhat a relevant topic.

A lunar calendar would be the Muslim calendar, while a solar calendar is the Georgian calender we use daily

Greetings, fellow worldbuilders!

Lately I have been devising the calendar used by the main civilization in my world, Ināvis, commonly known as Inavian Empire. This civilization is settled in a temperate area, therefore, their land experience seasons. There is also one moon, meaning they also observe moon phases. With this information I decided to build a lunisolar calendar for them to track both seasons and phases simultaneously, like several real-life calendars do (Hebrew, Chinese...).

In order to achieve this difficult task I studied thoroughly Artifexian's videos about creating solar, lunar and lunisolar calendars (I recommend them). Initially I tried to make my fictional year as long as Earth's, same with the lunar orbit, but soon I realized that I was copying reality and that I should create something entirely different (sadly, this also entails I cannot "translate" dates from my calendar to Gregorian calendar without brain-squashing calculations). Anyway, I set both the planet's orbit and the moon's orbit as 427.12 earth days and 32.30192 earth days respectively. Those are not arbitrary, but meaningful numbers to me, so I'm quite attached to these numbers for my fictional year and month.

The problem is: I am awfully terrible at maths. I need to have 13 months (devoted to the 13 preeminent deities) so I cannot find a way to make thirteen regular 32-day months with the moon phases falling always on the first day of the four 8-day weeks. This occurs, I think, because months are not 32 exact days long, but 32.30~.

In short, I need someone to clear my mind and help me find a good way to have 13 months with 32 days each to make a 427-day year without causing the moon to change phase on the next/previous day of the week. The picture attached to this post illustrates the "ideal" month I try to create.

Furthermore, I have some doubts:

1. Since the year is 427.12 days long: does this mean I need to add an extra day every eight years? (0.12*8=0.96).
2. Since the month is actually 32.30~ days long: does this mean I need to add an extra (intercalary) day every three months? Resulting in four intercalary days per year?

I'm aware I'm asking too much. The calculations for this are quite hard and elaborate. I tried to make these calculations with 412.27 as the year length and 32.70412, 32,80312 and 32.7412 as the month (lunar orbit) length, just in case these numbers are more fitting.

I accept any piece of advise and opinions about the model I devi

The following text seems to describe the traditional Lunisolar Calendar of the Khajiit of Elsweyr.

Origins

It is a belief deeply rooted in Athalã culture that the Gods can not rule the world symultaneously. Instead, each of the six gods comes into power - or as they say, "holds the staff of the world" - in accordance to the six cycles that the white moon does around the world in a solar year.

There was a time, the priests say, when the gods ruled as a exarch, but being unable to agree, their rule often resulted in disastrous civil wars that destroyed the world with earthquakes, floods and endless storms. Feeling compassion towards mankind, they decided to split their powers, creating the moons to establish how long each god would to rule - this myth shows how deeply entrenched the values of monarchy are in the Athalã's worldview.

The Traditional Lunar Calendar

Before the rule of the Great Thàm Gantaïssàn Bharaïnanã, the fifth king of the pre-imperial dynasty, the Athalã kept their time exclusively following the white-moon. The existance of a solar year was known of course, and the lenghtening and shortening of the days with the seasons had long been a noticeable feature for "skykeepers", but only the moon was considered important timekeeping devices. The red-moon was completely ignored as well.

The six seasons of the year were lasted as long as the six white moons and bore the gods' names.

The solar year canonically begun at middle of the Month of Storms (Eïtã, named after Eït, the god of storms, winter, stars and premonition), but the year officially started with the new moon of Thamoïn, the father god of the Athalã pantheon, thirty days later than that. The season called Thamoïnã or Month of Waters, corresponding to our february and march, is the period when the melting of the snow caps on the sacred mound causes the flooding of the rivers.

Sixty days later, as the moon renews once again, it's the turn of Herî, the mother goddess, to hold the staff. Her season, the Month of Blooms or Herinã, starts with the blooming of magnolias, her sacred flower, and corresponds to april-may.

It's followed by Alphèrã, The Month of War (june-july) and Adamosã, the Month of Harvest (august-september). The migration of the wandering birds kicks off the Month of Travellers, Hentã (october-november) ending with the Month of Storms.

Issues with the Traditional System

Unfortunately, the calendar devised by the Ancient Athalã didn't quite work. It wasn't long before the sky keepers noticed that it took only ten years for the white-moon to

As far as I know, the calendar depends on the moon, and a typical year has 353-355 days (why is it not a set number?) and that if it falls too far behind(?) they'll put a leap month to up the number of days in that year to 383-385 (so I assume they add exactly 20 more days to that?). Since I own a digital clock that shows the date in both Gregorian and Chinese lunisolar, there's definitely some mathematics involved to these day placements rather than just purely observational, or otherwise it'd be tedious to program such a clock, right?

Hello! Non Wiccan here, but I find Wiccan practices interesting. I'm also a huge nerd, and love calendar systems, astronomy, and math.

For those of you who don't know, a lunisolar calendar is a calendar system based on both the sun and the moon, not just one or the other. The calendar system most people use today (Gregorian) is solar, which means we divide each year up into 12 months, which don't really line up with the cycles of the moon. A lunisolar calendar, such as the Hebrew calendar, has each month lasting one lunar cycle, and adds a leap-month every 19 years or so, so the calendar lines up with the solar year. This way, if you know the date, you know not only the season of the year, but the phase of the moon.

As I understand it, Wiccans celebrate their holidays in accordance with the "Wheel of the Year", which is based directly off of the Gregorian calendar (Today is May 1st, so happy Beltane!). But, this seems very non-ideal for anyone interested in Astronomy/Astrology.

Does anyone here use, or consider using alternative calendar systems?
