12

12 is divisible by 2, 3 ,4, 6 12 plays a special role in astronomy because of the 12 year Jupiter cycle which also determines that there are 12 Signs of the Zodiac. Multiples of 12 play a fundamental role in mathematics: 1 12 24 36 48 60 72 84 96 108 120 132 144 Further multiples of 12 play a seminal role in astronomical and cosmological systems, especially: 12, 24, 36, 72, 108, 144, 216, 288, 432, 576, 720, 864, 1008, 1152, 1296, 1440, 1728 12 120 1200 12000 In India, 12 is linked with the Circle and creation: The circle is divisible by the product of four elements multiplied by three attributes. This involves the belief that the three attributes exist in the circle. By moving three times, each element completes its revolution. So now we have the number 12 {3 x 4}. This division gave birth to our 12 months, and also to the 12 horas {1/2 of the day or Ahoratri}. We now have 360 degrees as well as 12 divisions. We can now further divide the wheel of time: there are 27 fixed stars (nakshatras) along with three attributes that divide the time in smaller portions. So this 27 + 3 = 30 is interpreted as 30 degrees or days of one part of the wheel (circle) or month. All of this is only half of a day. The night is yet unaccounted for. Therefore, we multiply these 30 degrees by 2. This gives us our reference of 60 seconds in a minute. Thus the 360º x 30º = 10,800. Zero {0} is considered ‘Purna’ or complete. So we take out the last zeros and are left with 108. The idea of our total universe is represented by this number of 108. Offering 108, devotees believe that they are showing ultimate or complete respect to the Supreme. Cited from Website Hindu Astronomy
