The mansupi tachira ripōchya is the most recent of the tachira ripōchya (solar calendars) in the country of Kyōti. It consists of eight months ranging from forty-four to forty-seven days. To adjust the calendar for imperfect cycles, some months lose (“fall back”) one day every 4, 8, or 16 years. These fall days are in the appropriate years evenly divisible by their respective number.
- Furúchi: 46 days
- Netsúo: 47 days, fall day 1/4 years
- Myoràchi: 47 days
- Hizofūne: 44 days, fall day 1/8 years
- Kosobyòri: 47 days
- Jinòkyo: 46 days, fall day 1/16 years
- Saríchi: 45 days
- Dòte: 47 days, fall day 1/4 years
The years of the calendar are measured from the Hizogoma Betrayal and are abbreviated as “HB”.
The most common formatting for the dates is either the year, month, and day as 1-based numbers and separated by forward slashes.
- 1471/3/1 MTR
The long format for the date is the year, the full name of the month, and then the numeric day followed by “kāi” which means day. The kāi is omitted when obvious.
- 1471 Myorachi 1 kāi
- 1471 Rachi 1 kāi
When the calendar was first created, the initial months were named after the eight allies of Tachìra in his war against Chobìre.
- Kyodote richi goes from 46 to 47 days
- Sachikonu richi goes from 46 to 45 days
- 368 = Wo 46, Ne 46, Myu 46, Hi 46, Ko 46, Ji 46, Sa 45, Kyo 47
These were changes to the names of the months, mostly due to the translation between the different clan names and the largely oral tradition.
- Wochifumi ríchi becomes Wofuríchi
- Myuraku rìchi becomes Myoràchi
- Kosòbyo rìchi becomes Kosobyòri
- Sachikónu rìchi becomes Saríchi
- 368 = Wo 46, Ne 46, Myo 46, Hi 46, Ko 46, Ji 46, Sa 45, Kyo 47
- Myoràchi goes from 46 to 47 days
- Jiyokoni richi goes from 46 to 45 days
- 368 = Wo 46, Ne 46, Myo 47, Hi 46, Ko 46, Ji 45, Sa 45, Kyo 47
- Growing trade from the southern countries gives the concept of an eight-day week. Since eight is a holy number in the desert, this becomes quickly popular.
- Mapyózi, as a teenager, realizes that the calendar isn’t accurate enough. She spends the rest of her life traveling the desert to spread the understanding. This is also where the idea of giving an extra day and taking it away was the way to correct the calendar (instead of leap days as in our world). Later, she realizes that she wasn’t correct and commits suicide.
- Netsugio ríchi goes from 46 to 47 days, loses a day once every four years
- Kyodote richi loses a day once every four years
- 368.50 = Wo 46, Ne 46.75, Myo 47, Hi 46, Ko 46, Ji 45, Sa 45, Kyo 46.75
- Upset about the diminution of his clan’s name in the calendar spends his life trying to get it renamed back to the original name. He fails, but in the process of trying to garner favor, he shifts the days around before he failed his life’s mission.
- Myoràchi is reduced from 47 to 46 days
- Jiyokoni richi is increased from 45 to 46 days.
- Jiyokoni richi is changed to Jinòkyo
- 368.50 = Wo 46, Ne 46.75, Myo 46, Hi 46, Ko 46, Ji 46, Sa 45, Kyo 46.75
- Kosobyòri loses a day once every eight years
- 368.375 = Wo 46, Ne 46.75, Myo 46, Hi 46, Ko 45.875, Ji 46, Sa 45, Kyo 46.75
- The Hizogōma clan becomes one of the most famous of the clans to turn their back on Tachira and join forces with Chobìre.

Language continues to drift

- This was a politic reform in an attempt to “normalize” the calendar. It makes the leap days more evenly spread out through the year, continues the stealing of days from Hizofūne and shows the continual rise of the Kosòbyo clan.
- Hizofūne loses a day once every 1/8 years
- Kosobyòri no longer has a fall day
- Jinòkyo loses a day once every 1/16 years
