About these units
Baker's Dozen (13)
Thirteen items. Traditionally explained as medieval English bakers adding a thirteenth loaf to each dozen; the tie to bread-weight laws is plausible but unproven.
A baker's dozen is thirteen, one more than the twelve a customer asked for. The usual explanation is that medieval English bakers added an extra loaf to stay out of trouble under the Assize of Bread and Ale, which tied the price of bread to the price of wheat. Henry III revived the law in 1266, and bakers who sold short weight could be fined, pilloried, or flogged. The extra bread is traditionally called the vantage loaf or the in-bread.
How well attested is the story? The Assize and its penalties are well documented, and the early 15th-century London book Liber Albus describes an old custom of giving retailers 13 loaves for the price of 12, which one historian reads as a resale margin rather than a safeguard. The phrase itself is recorded only from the late 1500s, with Thomas Nashe in 1596, and no surviving record links it directly to the law. The Assize regulated weight, not count, so the tidy explanation has gaps. Reference sources differ in how firmly they accept the link, but none cites direct proof.
1 baker's dozen = 13 pieces (exactly).

Dozen (doz)
Twelve items. Eggs, rolls and many goods are still sold by the dozen.
Dozen entered English from Old French douzaine, a group of twelve, built from douze, which comes from Latin duodecim, plus a suffix that makes a collective. Twelve earned its popularity partly by dividing evenly: it splits into halves, thirds, quarters, and sixths, which helps when sharing goods. One suggestion is that the roughly dozen lunar months in a solar year made twelve one of the earliest groupings.
Even in a decimal age, dozens persist in commerce, often for foods such as eggs. Larger multiples extend the system by twelves: a gross is 12 dozen, or 144, and a great gross is 12 gross, or 1,728. The idiom six of one, half a dozen of the other uses the unit to say two options come to the same thing. Twelve also gave English the baker's dozen, which adds one more.
1 dozen = 12 pieces (exactly).
