Friday Farming. The basic unit.

"Forty acres and a mule".  The basic agrarian unit in the American east in the 19th Century, and hence the unit that freed slaves were hoping to obtain, with the basic animal necessary to work the same.

"Three acres and a cow."  The basic agrarian unit in the United Kingdom in the 19th Century and early 20th Century, and hence the slogan of land reformers and Distributists.
