While "days" and "weeks" still go by those names in Hadari, "months" and "years" and time frames have a different name.  You may recognize "moons" as months from the Warriors series, but here are other time frames:

Moon = one month/31 days
Juni tren = one year/12 moons
Jū kela = one decade/ten years
Kenti ju = 50 years
Dokenti ju = one centry/100 years
Li ke nairu = refers to one's lifetime (ex. "I've only been there once in my li ke nairu" or "His li ke nairu was a dokenti ju long before he died.")

So yeah... now you know :P

("Juni tren" and "jū kela" were half based off of the Japanese words for "twelve" and "ten," just so you know .-.)
