Manvantar / Manuvantar as per Puran :

Manvantar / Manuvantar or age of a Manu the Hindu progenitor of mankind is an astronomical period of time measurement. Manvantar is a Sanskrut sandhi a combination of words manu and antara, manu-antara or Manvantar literally meaning the duration of a Manu or his life span.

Each Manvantar is created and ruled by a specific Manu who in turn is created by Brahma the creator himself. Manu creates the world and its entire species during that period of time each Manvantar lasts the lifetime of a Manu upon whose death Brahma creates another Manu to continue the cycle of Creation or Shristi, Vishnu on his part takes a new avtar and also a new Indra and Saptarishis are appointed.

Eventually it takes 14 Manus and their respective Manvantars to create a Kalp or a 'Day of Brahma', according to the Hindu Time Cycles and also the Vedic timeline.

Thereafter, at the end of each Kalp there is a period of dissolution or Pralay wherein the world is destroyed and it lies in a state of rest during a period called the 'Night of Brahma'.

After that the creator Brahma starts his cycle of creation all over again in an endless cycle of creation followed by Destruction for which Shiv, Hindu God of destruction and also renewal is invoked towards the end of each such cycle.

Duration of a life cycle :

Brahma is said to have been created from the navel (which is a single point) of Vishnu, described as a lotus blooming out of the navel. The life span of Brahma is of 100 years (day time). During the day Brahma starts the creation process and at night Brahma goes to sleep (only Brahma goes to sleep not Shiv and Vishnu) and during the night all life he created is absorbed back into him. The creation and destruction is an ongoing process (repeated forever).

Brahma creates the universe, the universe maintained by Vishnu (The God of Preservation) and destroyed by Shiv (The God of Destruction). These three constitute the holy Trinity (Trimurti) of the Hindu religion. Once the universe has been destroyed by Shiv, Brahma starts the creation once again. This creation-destruction cycle repeats itself almost endlessly.

The entire time period of the universe is known as Kalp. "Kalp" equals to one day (day + night) of Brahma. Day means the existence period of the universe and night means the destruction period of the universe. The time period of day and night is same.

In the Hindu tradition Ved's were formed in the beginning of the universe. The counting of the time period of the begining of the universe is as following.

One day of Brahma (only day) is divided into 14 parts and each part is known as Manvantar.

Manvantar 1

Manvantar 3
Manvantar 4

Manvantar 7
Manvantar 8
Manvantar 9
Manvantar 10

Each Manvantar has 71 Chaturyug. Chaturyug is combination of 4 yugs (satyug, tretayug, dwaparyug and kalyug).

The life span of Brahma is of 100 years. Brahma's one day is called a kalp, the creation of Brahma is called vikalp and the creation of the total creation is called mahakalp.

In the Skand Puran, Brahma's thirty days are mentioned as :

1) Svet Varah Kalp
11) Dhyan Kalp
21) Som Kalp
2) Nilalohit Kalp
12) Sarasvat Kalp
22) Bhavan Kalp

4) Gathantar Kalp
14) Garud Kalp
24) Vaikunth Kalp
5) Raurav Kalp
15) Kaurm Kalp
25) Arcis Kalp
6) Pran Kalp
16) Narasimha Kalp
26) Vali Kalp
7) Brhat Kalp
17) Samadhi Kalp
27) Vairaj Kalp
8) Kandarp Kalp

9) Sadyat Kalp
19) Visnuj Kalp
29) Maheshvar Kalp
10) Isan Kalp
20) Saur Kalp
30) Paitr Kalp

Each day of Brahma is a duration of one thousand divya yug's. A divya yug cosists of one thousand of the four yug's. The same duration comprises his night.

These fourteen Manvantars had continued in past, are continuing in the present and they would continue in the future also. It is by them, that a Kalp (a period of thousand Chaturyug) is completed. Calculation of time is also done through these Manvantars.

Period of a Manvantra is slightly more than seventy one Chaturyug (all the four Yug's passing seventy-one times). A Chaturyug (period of all the four Yug's taken together) lasts for about 3 million years, while a Kalp lasts for about four thousand three hundred and twenty million years. This is equal to a day of Brahma. Brahma's night is Mahapralay (the great deluge). When that night is over, Brahma again begins the work of new creation exactly as per the previous Kalpa. Carrying out this responsibility continuously for a century, Brahma goes back to Bhagwad dham (the abode of Lord Vishnu).

His responsibilities are taken over by the next Brahma, who carries out the work of creation, by the inspiration of Lord Narayan.

Mahapralay (end of 14th Manuvantar)
