- The concept of Manvantara, while not mentioned in Mahabharata, is discussed by all 18 Puranas. Each daytime of Brahma (1 Kalpa) is divided into
**14 Manvantaras**. Each Manvantara has it’s own Manu, whose life spans the duration of the Manvantara. Thus

**1 Kalpa = 14 Manvantaras = 1000 Chatur Yugas**

So, 1 MANVANTARA = ~71.4 Chatur Yugas

- Some accounts equate 1 Manvantara to 71 Chatur Yugas, thus resulting in 14 x 71 = 994 Chatur Yugas per Kalpa. The remaining 6 Chatur Yugas (that are left due to the way 71.4 is rounded) are accounted for transition time
*preceding and succeeding* each Manvantara, with each transition lasting in duration equivalent to that of Satya Yuga (4800 divine years). Thus for 14 Manvantaras, the transition time is 15×4800 = 72,000 divine years = 6 Chatur Yugas.

- By other accounts, there are simply 72 Chatur Yugas per Manvantara, thus making 72 x 14 = 1008 Chatur Yugas in each Kalpa. Aryabhata, in his Aryabhatiyam (Ref: Dasa Gitika Pata, verse 3) supports this calculation. Thus,

** 1 MANVANTARA = 72 Chatur Yugas**

**1 Kalpa = 14 Manvantaras = 1008 Chatur Yugas**

** **

The divisions of time

** **

- The lifetime of Brahma is said to be 100 years, with 2 Kalpas accounting for a day (including nighttime). This entire lifespan is called
**Para**; half of this lifespan is called **Paraardha**;** **Thus Brahma’s life, consisting of 2 Paraardhas, is

**Lifespan of Brahma = 100 years x 360 days x 2 Kalpas/day = 311,040,000,000,000 years**

- Note that the calculation of Brahma’s lifetime does not depend upon how we account for each Manvantara, as it converts each Kalpa directly into 1000 Chatur yugas

There are about 9,815,675,904,000,000,000,000,000,000,000 nanoseconds in one Para. Just thought that you should know.

Note that in the article cited above the misinterpretation that half of Brahma’s life is over is challenged. If such were to be the case thousands of kalpas must have precede the current kalpa. The Vishnu and Bhagvata Puranas do not support such a possibility.

Noo… there exactly 71 chaturyugas in 1 Manvantara…

14 manvantaras = 71 * 14 = 994 chatuyugas

but between every Manvantara there a gap of time, which is equal to time period of krutha yuga…

krutha yuga = 0.4 * (1 chaturyuga)

therefore, in 1kalpa there are 14 manvantaras seperated by 15 gaps of krutha yugas

so, 1 Kalpa = 14*71 chaturyugas + 15 * (0.4 chturyugas)

= 994 chturyugas + 6 chturyugas

= 1000 chaturyugas

Also, for your information, In bhagavad Gita Krishna told that 1 kalpa is having 1000 chaturyugas… how can he would be wrong??

Akhil, I have stated different calculations for Manvantaras based on different texts/puranas. Your explanation is also covere (bullet #2).
