(Ed: for convenience of typing T and E are used here for ten and eleven)
I had never seen a *good* base 12 number system. Thus, I created this one (which hopefully is).
I have adopted a variant of the symbols for nine plus one and nine plus two as supported by the dozenal society of Great Britain.
Where I have deviated from normal numbers where you might not expect me to (eg. Nine = "en") I have done so for practical reasons only.
I have tried to create reasonable and distinct
sounding names, that are easy to say.
The "teens" are accommodated by the suffix -twe, and
the dozens beyond that by the suffix -do.
Occasionally, you may note "blips" in the spelling
such as ad + twe = addwe. This is a simple matter of
assimilation, that which occurs so that adjoining
consonants move to the same point of articulation etc
(for ease of speech). Thus, sometimes "-do" becomes
-to.
Occasionally, some vowels may also be missed (eg. One
+ twe = ontwe). This, too, is for pronounciation and
language reasons. Sometimes, though, I have not done
this when by pattern I should have - this is so as to
indicate pronounciation.

14 | Fortwe | |
15 | Fiftwe | (sometimes I pronounce this "fye-wee") |
16 | Sixtwe | (I have come to pronounce this as "sight-wee") |
17 | Septwe | (set-wee, set-way) |
18 | Addwe | |
19 | Entwe | |
1T | Dentwe | (sometimes denetwe - "den-et-way") |

100 | Gross | |
1000 | Grand | |
1,000,000 | Milliad | |
The present year, (2003ad) / 11TE ad = Ontwe Denedo elf (or) One grand, One gross and denedo-elf
As far as higher powers go, it depends really on whether you are using the one thousand million = 1 billion system, or the one million million = 1 billion system. I will not impose, but will say that the higher names are:
1 grand milliad (or) 1 milliad milliad = 1 billiad |
1 milliad milliad (or) 1 milliad milliad milliad = 1 trilliad |
1 grand^6 (or) 1 milliad^6 = 1 hexiad |
1 grand^*10 (or) 1 milliad^*10 = 1 uniad |
I hope you got that. I shall rephrase, in case you did not:
One dozenal "million" = 1 milliad
One dozenal "billion" = 1 billiad
One dozenal "trillion" = 1 trilliad
One trilliad times by one trilliad = 1 hexiad
One hexiad times one hexiad = 1 uniad.
The values are different, obviously, due to the two different number systems used worldwide.
Even higher numbers are formed in the usual way. That is, the numbers + iad (illion in decimal). So, Grossiad, for instance.
Afterwords/notes:
I reject the often-heard "-dek", amongst others, as I view them as aesthetically displeasing. If a number has to be changed, the goal is to make it easy to say, distinct, possibly vaguely English, and aesthetically pleasing (at least not distasteful).
The symbols I use for dene and elf are borrowed from Arabic, hence their strange style. These are as close as word can come to the *actual* dozenal symbols for these. Though, these symbols are almost exactly right, just move them up onto the line, and Romanise their curves. Dene is like a cursive t, and elf is a back-to-front *rounded* three.
I believe this to be a full and useful system of dozenal numeration. Obviously it is not "final", in as much as pronounciation changes, new ways are found to distinguish things, etc. (All comments welcome!).
