The Dozenal Society of America

Beginner to Dozenal?
Are you interested in using different number bases, or you’re studying number bases in school? This is a great place to start! Particularly if you're interested in dozenal (also called duodecimal, or base twelve), you've come to the right place! Not to mention our huge selection of articles and books. Soon, you'll be using twelve as a number base, multiplying and dividing, adding and subtracting, just as well (better!) than you ever did in decimal.
