1 kalpa is equal to 1000 Chaturyugas..1 Day of Brahma Loka is 1 Kalpa

1 Chaturyuga = 12000 deva years

■ 1 kalpa = 12000000 deva years
■ 12 hour of Brahmaloka= 12000000deva years
■ 1 hour of Brahmaloka=1000000 deva years
■ 1 second of Brahmaloka=277.7778deva years
■1 second of Brahmaloka=277.778×360 Human years
■1 second of Brahmaloka=100000 Human years

Thus in 1 second of Brahmaloka 1 Lakh Human year passes..

This means this Kaliyuga will just pass in 4.32 seconds for those who see from Brahma loka..

This means a chaturyuga passes in 43.2 seconds when seen from Brahma Loka..

This means a Manwantara passes in 12hour/14= 51 minutes when seen from Brahma Loka.

Let us apply this data in one interesting case of Bhagwat Puran in 9.3::

  1. Taking his own daughter, Revati, Kakudmi went to Lord Brahma in Brahmaloka, which is
    transcendental to the three modes of material nature, and inquired about a husband for her.
  2. When Kakudmi arrived there, Lord Brahma was engaged in hearing musical performances by the
    Gandharvas and had not a moment to talk with him. Therefore Kakudmi waited, and at the end of the
    musical performances he offered his obeisances to Lord Brahma
    and thus submitted his long-standing
  3. After hearing his words, Lord Brahma, who is most powerful, laughed loudly and said to Kakudmi: O
    King, all those whom you may have decided within the core of your heart to accept as your son-in-law
    have passed away in the course of time.
  4. Twenty-seven catur-yugas have already passed. Those upon whom you may have decided are now
    gone, and so are their sons, grandsons and other descendants. You cannot even hear about their

  5. O King, leave here and offer your daughter to Lord Baladeva, who is still present. He is most
    powerful. Indeed, He is the Supreme Personality of Godhead, whose plenary portion is Lord Visnu.
    Your daughter is fit to be given to Him in charity.

Lets calculate how much they remain in Brahma Loka. Brahma tells 27 chaturyugas have already passed.

As 1 chaturyuga = 43.2 seconds
    ■27 chaturyuga = 1166.4 sec= 19.44 min.

ie, They listened the music in Brahmaloka for about 19.44 minutes and during that time 27 chaturyugas already passed. She reached earth and married Balarama in 28th Dwapar..

Thus now remaining about 426884 years of Kaliyuga which seems so long for us just passes within 4.26 sec from Brahmaloka.

If a person lives for full 100 years in this Kaliyuga then from Brahmaloka that time passes just in 0.001 seconds.


What time is it now in Brahma's day?

There are 2 Kalpas in Brahma's full day of 24 hours not 1

1 kalpa for his 12 hour day

1 kalpa for his 12 hour night

A Catur yuga, Dvipa yuga and Maha yuga - ''A cycle of 4 Yugas''.

The Catur-yuga is also known as Divya-yuga or Maha-yuga and is made up of the four yugas -

''Satya- yuga, Treta-yuga, Dvapara-yuga, Kali-yuga''.

What time is it now in Brahma's day?

Lord Caitanya Mahaprabhu and Lord Krishna come in the 28TH Catur-yuga, Divya-yuga or Maha-yuga tn the 7th Vaivasvata Manu (current) Vamanajust "once" in Brahma's 24 hour day

We have already passed through 6 Manvantara's that each have 71 Maha-yugas in them

So presently we are in the 460th Maha-yuga in Brahma's 12 hour day out of 1000 making it 11.40 am in Brahma's daytime

The Manvantara's are created by a particular Manu who are all created by Brahma

Manvantara or Manuvantara or "Manvanter", or age of a Manu, the Vedic progenitor of humanity, is an astronomical period of time measurement. Manvantara is a Sanskrit word, a compound of manu and antara, manu-antara or manvantara, literally meaning the duration of a Manu, or his life span.

Each Manvantara is created and ruled by a specific Manu, who in turn is created by Brahma the Creator himself in this single Material Universe called Bhu-Mandala that is deep within our single enormous Brahmanda Egg shaped greater Universe that comes from the pores of Maha Vishnu's Body with billions of other Brahmanda egg shaped Universes .

Brahma creates the this single Material world called Bhu-Mandala however, all the billions of other Brahmanda's also have a similar Bhu-Mandala inner Universe and all have their own individual Brahmas.

There are billions of Brahma's ours has four heads others have 10 or 100 or 1000 or even 10,000 even 10 million! All depending on the size of their material Universe.

Also our Brahmanda that is over 44 quadrillion 444 Trillion miles 444 billion miles in diameter and inner Bhu-Mandala 4 billion sized very small Universe is very small compared to other Brahmandas and their inner Bhu-Mandala similar Universe.

Within our Bhu-Mandala Universe each Manvantara lasts the lifetime of a Manu, upon whose death, Brahma creates another Manu to continue the cycle of Creation or Shristi, Krishna's expansion Lord Vishnu on his part manifests a new Avatar.

Also a new Indra and Saptarishis are appointed.

Fourteen Manus and their respective Manvantaras constitute one Kalpa, Aeon, or a ‘Day of Brahma’, according to the Vedic Time Cycles and also the Vedic timeline.

Thereafter, at the end of each Kalpa, there is a period - same as Kalpa - of dissolution or Pralaya, wherein the world (earth and all life forms, but not the entire universe itself) is destroyed and lies in a state of rest, which is called the, ‘Night of Brahma’.

After that the creator of this single Bhu-Mandala Universe, Brahma starts his cycle of creation all over again, in an endless cycle of creation followed by absorption (annihilation) for which Shiva, Vedic demigod of Absorption and annihilation of this Universe, and also renewal, is invoked towards the end of each such cycle.

Duration of a Manvantara

The actual duration of a Manvantara, according to the Vishnu Purana is seventy one times the number of years contained in the four Yugas, with some additional years, adding up to 852,000 divine years, or 306,720,000 human years.

Seven Rishis, certain (secondary) divinities, Indra, Manu, the king and his sons, are created and perish in one interval (called a Manvantara) equal to seventy-one times the number of years contained in the four Yugas, with some additional years.

This is the duration of the Manu, the (attendant) divinities, and the rest, which is equal to 852,000 divine years, or to 306,720,000 years of mortals, independent of the additional period.

Fourteen times this period constitutes a Bráhma day, that is, a day of Brahmá; the term (Bráhma) being the derivative form. The Brahma life span is 100 Brahma varshas. The following table will illustrate clearly the link to our years and Brahma years.


1 human year (in Hindu calendar) = 1 Deva Ahoratra for God (1 day and 1 night)

360 Deva Ahoratras = 1 Deva Vatsara

12,000 Deva Vatsara = 1 Chaturyuga

(12,000 Deva Vatsaras are defined as, 4,800 Deva Vatsaras of satya yuga, 3,600 Deva Vatsaras of Treta Yuga, 2,400 Deva Vatsaras of Dvapara Yuga and 1,200 Deva Vatsaras of Kali Yuga (which is 1,200 * 360 = 432,000 human years); summing up to 12000)

71 Chaturyugas = 1 Manvantaram (1 life span of Manu)

14 Manvantaras = 1 kalpa (1 day of Brahma)

2 Kalpas = 1 day and 1 night 24 hour period + 1 Brahma ratra

360 days of Brahma = 1 Brahma varsha

Comparison to the Age of the Universe from Modern Astronomy

Modern scientific astronomy estimates the Age of the Universe as around 13 Billion years (13 * 109 years).

Conversion of 1 day-night of Brahma into human years yields 8.58816 * 109 years (derived as 2 kalpas * 14 Manvantaras * 71 Chaturyugas * 12,000 Deva vatsaras * 360 human years).

According to Vedas, there are 504 000 Manus manifested during the lifetime of one Brahmā (311,040,000,000,000 human Earthly years), 5,040 Manus in one year of Brahma, and 420 Manus in one month of Brahma. (See for more details: List of numbers in Hindu scriptures.)

Then night-time comes which is also 4 billion 320 million human years long. At night while Brahma sleeps and creates no Chatur-yuga or Maha-yugas, our Universe is partially annihilated.

When the next day-time arrives at sunrise the cycle repeats itself for every day and night of Brahma's life

We are in the 28th Chatur-yugas or Maha-yuga in the ''Vaivasvata Manu'' (current) that has 71 Maha-yugas in it.

71 Chatur-yugas = 1 Manvantara (1 life span of Manu)

We are in the 460th Maha-yuga also known as a Chatur-yuga

At night while Brahma sleeps and creates NO Chatur-yuga or Maha-yugas, our Universe is partially annihilated.

When the next day-time arrives at sunrise the cycle repeats itself for every ''day and night'' of Brahma's life
