A day on Daia is 72,000 s, or 20 hr, long; it is divided into sixteen
natai (sg.
nata). A
nata is divided into 72
qarenaw (sg.
qaren), and a
qaren is divided further into 72
đagiai (sg.
đagia), matching the ideal safir resting heart rate of 69.12 bpm.
Above a day, the next timekeeping period is a
kateme, a rather informal period of nine or ten days. Above that is the second, rarer, definition of
vàtaře, which refers to a period of 40 days.
Then there is the Daian year, equivalent to 549 local days (457.5 Terran days; 1.25 Terran years).
Then there is the Daian calendar, which is fairly unique, by human standards, in its operation.
It eschews weeks and months, instead having two “wheels”: one 429 days (357.5 Terran days; the idealized safir gestation period) and one 549 days. The former names days by numbering them 1-33 and naming them after thirteen of the fourteen deities of Ilâþnarâri, in this order:
- Aume
- Kieri
- Kaêna
- Amahira
- Tarin
- Vâla
- Sila
- Mismar
- Anzu
- Palařo
- Enâra
- Valora
- Erina
(Âmâne's name is lent to leap days, which occur once every 11 years.)
The 549-day wheel names days by numbering them 1-61 and naming them after nine colors, as follows:
- Sajúmas (brown)
- Cavartûs (yellow)
- Âfełaris (green)
- Mátsunas (black)
- Basîres (pink)
- Menaós (dark blue)
- Ìtreus (orange)
- Ávris (red)
- Îceilis (purple)
No day name repeats for 143 Daian years; this is the far more common use of
vàtaře, which lends itself to year numbering. Years are numbered based on their cycle and position within.
As I write this (June 7th, 2021, at 11:20 AM EDT), it is 5 Anzu 54 Cavartîs, in the 40th year of the 35th cycle (4902 AC). This is close to the end of the year; the new year will begin on the 14th, at 4 AM. The most recent cycle began at the Unix epoch (January 1st, 1970, at 12:00 AM UTC).
