Baker's Dozen Day

Isn't 'baker's dozen' an interesting expression.  Dozen may be one of the earliest primitive groupings.  It is also known as a devil's dozen or long dozen.   The expression came about with baked goods, as a way for bakers to avoid being blamed for shorting their customers.  Bakers had to sell goods by the dozen at a specific weight.  The expression evolved over the centuries to further variations around this intent. While most things aren't sold by the dozen anymore, we still an buy a dozen eggs.  This is common everywhere. They started out being sold by the dozen to match up with the Anglo-Saxon and Roman systems of measurement.  One egg could be sold for a penny or 12 for a shilling.  This persisted in the American colonies, after the revolution.  And it just stayed after that.
