Principles
There are three qualities that distinguish one year from another: whether it is a leap year or a common year, on which of four permissible days of the week the year begins, and whether it is a deficient, regular, or complete year. Mathematically, there are 24 (2×4x3) possible combinations, but only 14 of them are valid. Each of these patterns is called a keviyah (Hebrew קביעה for "a setting" or "an established thing"), and is encoded as a series of three Hebrew letters.

Famous quotes containing the word principles:
“It is a life-and-death conflict between all those grand, universal, man-respecting principles which we call by the comprehensive term democracy, and all those partial, person-respecting, class-favoring elements which we group together under that silver-slippered word aristocracy. If this war does not mean that, it means nothing.”
—Antoinette Brown Blackwell (1825–1921)
“...at this stage in the advancement of women the best policy for them is not to talk much about the abstract principles of women’s rights but to do good work in any job they get, better work if possible than their male colleagues.”
—Virginia Crocheron Gildersleeve (1877–1965)
“It is always easier to fight for one’s principles than to live up to them.”
—Alfred Adler (1870–1937)
