Historical Context

The Baker's Dozen Story

In medieval England, bakers faced heavy penalties for selling underweight bread. To avoid fines and punishment, they added an extra loaf to every dozen - the "vantage loaf" - creating the baker's dozen of 13.

Duodecimal System

Base-12 counting was common in ancient civilizations. You can count to 12 on one hand using your thumb to count the 12 finger segments on your other four fingers, making dozens natural for trade.
