Age of Earth and Brahma

The Hindu cosmology and timeline is the closest to modern scientific timelines and even more which might indicate that the Big Bang is not the beginning of everything but just the start of the present cycle preceded by an infinite number of universes and to be followed by another infinite number of universes. It also includes an infinite number of universes at one given time. Based on the evidence from radiometric age dating of meteorite material age of the Earth is 4.54 ± 0.05 billion years (4.54 × 109 years ± 1%). This is also consistent with the ages of the oldest-known terrestrial and lunar samples.

The puranic view asserts that the universe is created, destroyed, and re-created in an eternally repetitive series of cycles. In Hindu cosmology, a universe endures for about 4,320,000,000 years (one day of Brahma, the creator or kalpa) and is then destroyed by fire or water elements. At this point, Brahma rests for one night, just as long as the day. This process, named pralaya  repeats for 100 Brahma years (311 Trillion, 40 Billion Human Years) that represents Brahma’s lifespan. Brahma is regarded as a manifestation of Brahman as the creator.

In current occurrence of Universe, we are believed to be in the 51st year of the present Brahma and so about 156 trillion years have elapsed since He was born as Brahma. After Brahma’s “death”, it is necessary that another 100 Brahma years (311 Trillion, 40 Billion Years) pass until a new Brahma is born and the whole creation begins anew. This process is repeated again and again, forever.

The present period is the Kali Yuga or the last era in one of the 71 Chaturyugas (set of four Yugas/eras) in the life one of the fourteen Manus. The current Manu is said to be the seventh Manu and his name is Vaivasvat. According to Aryabhata, the Kali Yuga began in 3102 BC, at the end of the Dvapara Yuga that was marked by the disappearance of Krishna avatar.

Brahma’s Life span

1 human year         = 1 divine Ahoratra (Day and Night)

360 divine Ahoratra = I divine year.

4800 Divyavarsas = 1 Satya yuga

3600 Divyavarsas = 1 Tretayuga

2400 Divyavarsas = 1 Dvaparayuga

1200 Divyavarsas = 1 Kaliyuga

12000 Divyavarsas = 1 Caturyuga

71 Caturyugas   = 1 Manvantara

14 Manvantaras = 1 Pralaya/Kalpa

1 Pralaya (Kalpa) = Brahma’s one day.

This is equal to 4.29 billion years, which is the closest to the scientific calculation of the life of Earth and solar system.

2 Kalpas  = One day (and night) for Brahma. (Ahoratra)

360 days of Brahma 1 Brahma Varsa

100 Brahma Varsas One Brahma’s life-span.

This life-span of one Brahma is therefore 30917376000000 years of human beings.

Average Life span of various species is as given below. As you can see, in your life time, there would be many generations of flies and rats that would have come and gone.

A small story to illustrate the above.

Before the period of Krishna, the island Dwaraka was known as Kusasthall. It was ruled over by a famous King named Revata. This king had hundred sons and a daughter named Revati. When the time for marriage of his daughter came the King was anxious to find a fitting husband for her and went to Brahmaloka to take the advice of Brahma. Revati also accompanied him. There the eternal Rishis, Siddhas, Gandharvas, Pannagas and Charanas were singing hymns to Brahma in his praise. Standing with folded hands he waited a while to find an opportunity to talk to Brahma but was so very pleased with the music that he could not desist from hearing it till the end. When the music finished, the King bowed down to Brahma and showed him his daughter and informed Him of his intention.” O King! The princes that you thought would become the bridegroom for your daughter, all died; their sons and grandsons and their friends even have all passed away. The twenty-seventh Manvantara of the Dwapara Yuga is now going on; so none of the princes of your family now exist. Now Ugrasena, the King of Mathura, is reigning in that place. He belongs to the illustrious lunar family of Yayati. His son, the powerful Kansa, threw his own father to the prison. Baladeva, the elder brother of Krishna, carrier of the plough, is a great warrior and the part incarnation of Ananta Deva. He is the fit bridegroom of your daughter. So give your daughter in marriage, without any delay, according to the rules of the marriage ceremony to him.

Finally a joke. Once a devotee asked Brahma – I understand that your one day is equal to 4.3 billion human years, which means your one rupee would be 4.3 billion of humans, isn’t it? Yes, said Brahma. Sir, please give me a rupee, said the devotee. Brahma “ No problem, please wait for a day.

    I studied your explanation concerning time but you forgot to tell the length of Hindu Synodic Month as 29.5309973 days, and Tropical Year as 365.2 days. Did you know that Hindu Units are not proved in 46 BCE/45 BCE when Julian Calendar was introduced by Julius Caesar? I disproved the Hindu Units. What foolishness you explained. Don’t cheat Hindus henceforth because Hindu Astronomy is fit for nothing. For the details, please visit
    Thank you,
