The word for a year is "weton".  Wetona are divided into 5 yorona.
The yorona are: Yorokint, Yoroguln, Yoropite, Yorofyk, and
Yorosorn.  Yorokint, Yoroguln, Yorofyk, and Yorosorn each have
26 irtona, while Yoropite has only 25 irtona.  Hence there are 129
irtona in a weton.  Irtona are also grouped into sirona.  Each siron
includes 9 irtona.  Thus there are exactly 14 1/3 sirona in a weton.
The irtona of the siron are called Sirodon, Siroli, Siromeyn,
Sirovort, Sirokoga, Sirohain, Sirotro, Sirocotsi, and Sirozir.  Each
irton lasts for 19 alona.  Each alon consists of 85 riilona, and each
riilon contains 100 dikona.

In Lorasa Isten there are no terms for seasons.
