DozensOnline FORUM Introduction to Base Twelve

Many people nowadays know that there are counting systems other than the usual decimal one; they will have heard of base two (binary) and base sixteen (hexadecimal) because the computer uses the former and colour codings are usually expressed in the latter. Neither is used in everyday calculations. The computer accepts data in base ten and churns it out again in base ten; how the computer does its work interests few of its users and what numbers it uses in its innards even fewer. The computer is quite happy with base two and people use base ten because they are used to it and know of no alternative.

Is any one number base intrinsically better than another and more suitable for human calculations and daily work?

There are, and have been for many years, people who maintain that base ten is not the best choice for humans.

Some people think base sixteen might be a good substitute for base ten to bring humans more in line with their computers, but base sixteen requires several new symbols and provides few arithmetical benefits for humans.

But long before either hexadecimal or binary became familiar words, and before and ever since the French invented the metre and the decimal metric system, decimal notation and base ten have had a rival: base twelve.

Base twelve (also known as dozenal and originally as duodecimal) has long been singled out as a possible replacement for base ten. It offers many advantages over base ten.

So: could a change of number base really bring benefits to man?
We believe it will. You will find arguments and ideas in favour of base twelve in the pages on this site and also at the Dozenal Forum, where you can post your ideas and comments and discuss dozenals, decimals and what have you..

A fact or two:

Any and every type of calculation which can be carried out in base ten can be carried out in base twelve or in any other base one might choose.

The merits of base twelve are due to the great factorability of the number twelve, the next really useful number being sixty, but sixty is rather too large for an every-day number base. Ten is unsatisfactory because its factors 2 and 5 include the prime 5 which in turn is not as useful as the prime 3 (though one professor of mathematics complained that I was not being really fair to the number 5 when I said this ... ). The dozen, and the dozen dozen, or gross, have shown their usefulness in packing and packaging over many, many years.

And will Mankind be interested enough to listen? or kind enough? We live in hope

Aye, its counting, Jim, but not as we know itBut just consider, for a moment ... What would happen, if ...?

Now there's a thought to boggle the mind... Suppose we changed the number base, just like that, what would tomorrow be like? For the implications, have a look at "Splash!".

So its nothing but base twelve here?

No, there's more, all mathematical, - other bases, number puzzles, units of measure (including historical), important essays, some metric-bashing, - and more to come as we develop different areas.

Magazine: We no longer publish a regular Newsletter or magazine - all new work appears either here or in the Dozenal Forum, which has attracted many new members with valuable ideas and comments. Our pages here average some two hundred visits each week.The last Dozenal Journal we sent out to members is available for download: Journal as are other digital editions of previous publications.

Issues of the Journal and previous DSGB magazines are being digitized and several are available for download. This, and revision and editing of DSGB website pages, will be occupying us for some time.

With effect February 2017 Shaun Ferguson retired from the posts of Secretary and Treasurer of the DSGB, and Bryan Parry has taken over those posts.

Bryan can be contacted on home email, and on dsgb email

December 2020: New website is now being designed by Brian. Details will be posted here later.

Most recent changes (November 2020): Several hyperlinks updated and some removed:
January 2018: More DSGB magazines digitised; some editing and tidying of the "Basics" section, "Dozenite system" by Pasumarty added; New dozenal url references, Dozenal apps from the DSA.
"Splash" section revised and extended; New dozenal clock for your desktop (java) - in Applications; "Hamburg Musical Notation" added to application section; TGM (pdf archive of first edition); revised TGM booklet (pdf: spellings, spacing, general corrections), DSGB Newscast Archives added (Magazines in pdf format). These pdf versions of the Duodecimal Newscast have been produced for us by the DSA from scans of the original magazines. More will be published here in due course.

Student Projects.

We have had many enquiries from students who are studying base twelve for their mathematical project.
(Everyone gets a reply, by the way.)

All the information they require is to be found on this website and on that of the DSA, but questions are always welcome. Many of the answers about the advantages of dozenal (and the disadvantages of decimal) are to be found in the writings of members of the DSGB and have been published in our magazines - of which I would draw attention to our Dozenal Journals edited by Donald Hammond, and to be found listed in the literature section of this site. They are in pdf form for download and further study. They also contain some rich mathematical content relevant to the study of numbers and their practical applications.

a few words about us...

The DSGB, The Dozenal Society of Great Britain (founded 1959) and the DSA, The Dozenal Society of America (founded 1944) are separate organisations with a common aim: to draw attention to the advantages of the Dozen (or twelve-based) system for numeration and measurement. We consider that the decimal system is inadequate and of limited competence in many aspects of numeration. Decimals handicap the teaching of arithmetic and so inhibit understanding of the physical world and the decimal system is unable to express in simple terms the common proportions by which we order our practical and economic activities.

Membership of the Societies is open to all who have an interest in the development of arithmetic and measuring systems as vital tools for our everyday affairs and in promoting a clearer understanding of the ways in which the physical world is defined and ordered.By advocating the adoption of a more flexible numbering system for both scientific and general use we are also supporting the opinions of many philosophers and mathematicians, both past and present.
