Dozenal

Dozenal is a way of counting different than decimal. In decimal, we count in tens, whereas in dozenal we count in twelves. Numbers in dozenal are marked by "z;" and numbers in decimal are marked by "d:", so:

z;14 = d:16

Naming:
Because there are different numbers, there have to be different names. We can't call z;14 fourteen, because it's twelve and four, not ten and four. If you don't want to have to do complicated calculations yourself, use this handy-dandy tool: Dozenal-Decimal
