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:
“My country is bleeding, my people are perishing around me. But I feel as a South Carolinian, I am bound to tell the North, go on! go on! Never falter, never abandon the principles which you have adopted.”
—Angelina Grimké (1805–1879)
“I cannot consent that my mortal body shall be laid in a repository prepared for an Emperor or a King—my republican feelings and principles forbid it—the simplicity of our system of government forbids it.”
—Andrew Jackson (1767–1845)
“In child rearing it would unquestionably be easier if a child were to do something because we say so. The authoritarian method does expedite things, but it does not produce independent functioning. If a child has not mastered the underlying principles of human interactions and merely conforms out of coercion or conditioning, he has no tools to use, no resources to apply in the next situation that confronts him.”
—Elaine Heffner (20th century)
