Base-12 is a positional number system of counting based on the number cycle from 0 to 11.

Also, called the duodecimal or dozenal system, base-12 has been around for ages but has been all but replaced in modern times by the base-10 or decimal system which counts in cycles of ten, from 0 to 9.

However, we still use base-12 (and its big brother base-60) in a few notable areas such as measuring time in months, hours, minutes and seconds, rotational angles in degrees, geographic/GPS coordinates in degrees, minutes and seconds and, of course, beer and doughnuts by the delectable dozen.

Although having ten fingers may make it easier to count in base-10, base-12 is hands-down better for a number of reasons:

Base-12 can be divided five ways (in half, thirds, quarters, sixths, twelfths) versus only three ways in base-10 (in half, fifths, tenths). Also, base-12 aligns with the base-4 rotational structure of complex numbers through which the higher dimensional math of nature can be is expressed, but not base-10.

More balanced geometrically:

The four positions on the base-12 cycle where primes can occur (1, 5, 7, 11) are rotationally balanced, but not so on the base-10 cycle (1, 3, 7, 9).
