Daian timekeeping
Anthologica Universe Atlas / Universes / Safir Alliance / Classical Âirumâli / Daian timekeeping

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:

  1. Aume
  2. Kieri
  3. Kaêna
  4. Amahira
  5. Tarin
  6. Vâla
  7. Sila
  8. Mismar
  9. Anzu
  10. Palařo
  11. Enâra
  12. Valora
  13. 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:

  1. Sajúmas (brown)
  2. Cavartûs (yellow)
  3. Âfełaris (green)
  4. Mátsunas (black)
  5. Basîres (pink)
  6. Menaós (dark blue)
  7. Ìtreus (orange)
  8. Ávris (red)
  9. 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).
