The Dozenal Society of America
The DSA is a voluntary, nonprofit education corporation, organized for the conduct of research and education of the public in the use of dozenal (also called duodecimal or base-twelve) in calculations, mathematics, weights and measures, and other branches of pure and applied science.

Annual Meetings

The Dozenal Society of America holds at least one meeting a year, traditionally called simply “the annual meeting.” This is held most often in New York City, but it has been held in many other cities all across the country in the past.

The 1205 (2021) annual meeting will almost certainly be held purely virtually; further details will be posted as they become available.
