Why 12?

The following are just snippets of the significance and meaning of the number 12 in our life taken from various sources worldwide.

1. The word "twelve" is the largest number with a single-morpheme name in English. 1
2. Twelve is a perfect number, signifying perfection of government, or of governmental perfection. It is found as a multiple in all that has to do with rule. The sun which "rules" the day, and the moon and stars which "govern" the night, do so by their passage through the twelve signs of the Zodiac which completes the great circle of the heavens of 360 (12 x 30) degrees or divisions, and thus govern the year. 2
3. Twelve is the product of 3 (the perfectly Divine and heavenly number) and 4 (the earthly of what is material and organic). While seven is composed of 3 added to 4, twelve is 3 multiplied by 4, and hence denotes that which can scarcely be explained in words, but which the spiritual perception can at once appreciate, viz., organization, the products denoting production and multiplication and increase of all that is contained in the two numbers separately. The 4 is generally prominently seen in the twelve. 3
4. Twelve is the number in scripture which is one more than eleven; eleven being the number of the disintegration of fleshly perfection, twelve reverses that process of disintegration. Twelve is therefore the number which demonstrates spiritual foundation, spiritual perfection and completion. This is true whether it is concerned with the seed of the serpent as symbolized by Ishmael and his "twelve princes," or whether it is dealing with the seed of the woman, as symbolized by Isaac who later, after the natural was manifested first, had Jacob who also had 'twelve princes.' 4
5. The number 12 is strongly associated with the heavens—the 12 months, the 12 signs of the zodiac, and the 12 stations of the Moon and of the Sun. The ancients recognized 12 main northern stars and 12 main southern stars. There are 24 = 2 × 12 hours in the day, of which 12 are daytime and the other 12 nighttime. The number 12 is the product of the sacred and the secular (3 × 4); it is the sum of the numbers of life and good fortune (5 + 7). It thus incorporates many distinct virtues. In Christianity it is the number of Christ’s disciples, and it occurs many other times in the Bible—for example, the Twelve Tribes of Israel. Several cultures have used numbers based on 12 (duodecimal); the 12 inches in a foot are one familiar relic of such a system. 5
6. The number 12 is the most ancient of the "combination numbers" being the first actual combination which can be made without duplication in the Arabic numeral system. It is equivalent to the letter z, which Americans pronounce "zee" and Canadians pronounce "zed 6
