# How old is earth according to Hinduism?

I'm just curious to know, How old is earth according to hinduism?

As of science it is 4,500,000,000.

If we calculate this 4.5 billion years into Hinduism, 1041 Mahayugas, which is equal to 1 kalpa i.e 1 day of lord Brahma. But as of Hinduism, 50 years of lord Brahma have elapsed and this is the first 'day' of the 51st year.

According to Hinduism calculations based on age of lord brahma, age of earth must be 155,521,972,949,115 years. If lord brahma created earth on his first day of his birth.

I found one link which states, according to Hinduism earth is created and destroyed for regular intervals of time. Is that true?

• Are there any texts that mention about age of earth in Hinduism? Or

• Did Hinduism mention when and where it was created (any belief)?

Please give brief explanation on this topic.

• Yes Hinduism does talk about a creation and liberation concept after every interval. bhagavad-gita.org/Gita/verse-09-07.html.

• 1. It is correct that the universe is created and destroyed in mahapralaya and created again. 2. See this for calculation of the universe's age en.wikipedia.org/wiki/Hindu_cosmology But remember that this is only for the current Brahma's reign. Noone knows how many Brahma's preceded the current one and how many are forthcoming. For information, Lord Anjaneya is the next Brahma. There are already two Indras-in-waiting, viz, Bali Chakravarti and Raja Harischandra.

• @moonstar2001 that's interesting. I would love to see some source regarding "Lord Anjaneya is the next Brahma"

• @moonstar2001 "Noone knows how many Brahma's preceded the current one and how many are forthcoming." This chapter of the Shanti Parva of the Mahabharata describes six Mahakalpas before the present one, but of course that may not be exhaustive: sacred-texts.com/hin/m12/m12c048.htm Commented Mar 2, 2015 at 13:52
• @KeshavSrinivasan That is perhaps only the extent to which sages have chosen to reveal to the world. Scriptures also indicate that the skull-garland around Siva's and Kali's neck are actually skulls of Brahmas-past and are said to be infinite in number.

Time between begining of creation and beginign of destruction is kalpa (day of brahma) = 4.32 billion years

Age of earth according to modern radiometric data is around 4.54 billion years(As you have quoted)

Puranas quotes that currently we are in 7 th manvantara , 28th mahayuga of current kalpa.

So age of earth =

``````= 6 * Years for Manvantara + 28 * Years for mahayuga
= 6 * 306.72mil            + 28 * 4.32 mil
= 1.92 billion years
``````

But I am not sure , why it would be roughly half estimated time by science.
