Vedic Calculation of Time

The sun and moon are moving at scheduled times which have been meticulously calculated by our great sages long long past. (now scientists says in atom also electron and protons are moving around neutron in both living and non living things.) Until today we have not seen any difference in their calculation which is based on the soundest theory of "Ajapa Gayathri". It is based on the Mantra or Hymn called Hamsa, which is connected with inhalation and exhalation of human breath. The sound Ha represents inhaling and the sound 'sha' is caused while exhaling. Control over the breath is the basic principle of Pranayama. When breath is controlled mind is controlled too.The Fleeting nature of mind been controlled, it can be concentrated on divine thoughts. As a swan (hamsa) is to be kept under control for utilising its services,the mind is to be brought under swayby controlling the breath,the hymn of Hamsa or Ajapa Gayathri. According to medical investigation, the normal healthy man has 15 breaths per minute or 21,600 breaths per day.

In ancient India system to calculating time,

• 60Nadis = 1 Vinadhi.
• 60 Vinadhi or 3600 Nadis = 1 Nazhigai.
• 60 Nazigai = 1 day.
  
• 360 days = 1 year (Because of slowing down of earth, a year is now a little more than 365 days)
  

• Kali Yuga = 4,32,000 years.
  
• Dwapara Yuga = 8,64,000 years
  
• Trata Yuga = 12,96,000 years
• Krita Yuga = 17,28,000 years
  

• Mahayuga or Chatur Yuga = Kali Yuga + Dwapara Yuga + Trata Yuga + Krita Yuga = 43,20,000 years

1 kalpa or a day of Brahma = 1000 Mahayuga
1Manvantraa = 71 Maha Yugas

One full day of Brahma or Kalpais = 14 x 71 (or 994) MahaYugaas + the morning and evening (santhis of 6 Maha yuga) = 1000 Mahayugas.

So, 1 day in Brhama's day = 1000 x 43,20,000 years.
One year for Brahma = 360 such days of Brahma.

A day of Brahma is stated to be a period when all planets return to the same point in the sun or the first point of Aries at Horizon of Lanka on the equator, whose longitude is 76 degrees east of Greenwich.

There is a mystic link between the Mantra-Hamsa or Ajapa Gayathri and the period of Brahma, Vishnu, and Siva. The number of breathing per day 21600 (200 x 108). The number 108 has very great mystic power. The Upanishads are 108, Vishnupeethas or Diviyadesam are 108.
Our Hindu calender was calculated from the time when all the planets started their journey and not on the day of great man's birth or great king's birth.

According the Hindu mythology, during the day time of Brahma; he creates the life and during the night it is destroyed by Lord Siva. After the life time of Brahma, new galaxy will be created by new Brahma.
