Hindu units of time
Hindu units of time are described in Hindu texts ranging from microseconds to trillions of years, including cycles of cosmic time that repeat general events in Hindu cosmology.[1][2] Time (kāla) is described as eternal.[3] Various fragments of time are described in the Vedas, Manusmriti, Bhagavata Purana, Vishnu Purana, Mahabharata, Surya Siddhanta etc.[4][5][6]
Sidereal metrics
[edit]
Sidereal astrology maintains the alignment between signs and constellations via corrective systems of Hindu (Vedic)-origin known as ayanamsas (Sanskrit: 'ayana' "movement" + 'aṃśa' "component"), to allow for the observed precession of equinoxes, whereas tropical astrology ignores precession.[7] This has caused the two systems, which were aligned around 2,000 years ago, to drift apart over the centuries.[7][8]
Ayanamsa systems used in Hindu astrology (also known as Vedic astrology) include the Lahiriayanamsa and the Raman ayanamsa.[9] The Fagan-Bradley ayanamsa is an example of an ayanamsa system used in Western sidereal astrology.[9] As of 2020, sun signs calculated using the Sri Yukteswar ayanamsa were around 23 degrees behind tropical sun signs.[7] Per these calculations, persons born between March 12 - April 12, for instance, would have the sun sign of Pisces.[7] By contrast, persons born between March 21 - April 19 would have the sun sign of Aries per tropical calculations.[10]

Lifespans
[edit]Hindu texts define lifespans differently for humans, Pitris (forefathers), Devas (gods), Manus (progenitors of mankind), and Brahma (creator god). The division of a year for each is twelve 30-day months or 360 days, where a day is divided into a 12-hour day proper and 12-hour night.[20] A 30-day month amounts to four 7-day weeks with an extra 8th day every two weeks (48-week year). A traditional human year is measured by the sun's northern (uttarayana) and southern (dakshinayana) movements in the sky,[d] where the new year commences only when the sun returns to the same starting point and a pause on the commencement otherwise. Ebenezer Burgess postulates an intercalary month was inserted every five years to anciently maintain the correspondence of the 360-day years with the true solar years (~365.24-day years).[21] For this reason, a traditional 360-day year is equivalent to a modern ~365.24-day solar or tropical year.
| Unit[b] | Human | Pitri | Deva | Manu | Brahma |
|---|---|---|---|---|---|
| Brahma year | 3,110,400,000,000 yr | 103,680,000,000 yr | 8,640,000,000 yr | ~1,014,084.51 yr | 1 yr |

Cosmic date
[edit]According to Puranic sources,[e] Krishna's departure marks the end of the human age of Dvapara-yuga and the start of Kali-yuga, which is dated to midnight on 17/18 February 3102 BCE of the proleptic Julian calendar. We are currently halfway through Brahma's life (maha-kalpa), whose lifespan is equal to the duration of the manifested material elements, from which Brahma manifests his universe in kalpa cycles:[27][28][29][30][31]
- 51st year of 100 (2nd half or parardha)
- 1st month of 12
- 1st kalpa (Shveta-Varaha Kalpa) of 30
- 7th manvantara (Vaivasvatha Manu) of 14
- 28th chatur-yuga of 71
- 4th yuga (Kali-yuga) of 4
A maha-kalpa is followed by a maha-pralaya (full dissolution) of equal length. Each kalpa (day of Brahma) is followed by a pralaya (night of Brahma or partial dissolution) of equal length. Preceding the first and following each manvantara is a manvantara-sandhya (connection period), each with a length of Krita-yuga (a.k.a. Satya-yuga).[27][28]
Hindu texts specify that the start and end of each of the yugas are marked by astronomical alignments. This cycle's Treta-yuga began with 5 planets residing in the "Aries" constellation. This cycle's Dvapara-yuga ended with the "Saptarshi" constellation (Ursa major) residing in the "Magha" constellation. The current Kali-yuga will end with the Sun, Moon and Jupiter residing in the "Pushya" sector.[32][better source needed]
Human
[edit]The history of humanity is divided up into four yugas (a.k.a. dharmic ages or world ages)—Kṛta-yuga (pronounced Krita-yuga; a.k.a. Satya-yuga), Tretā-yuga, Dvāpara-yuga and Kali-yuga—each with a 25% decline in dharmic practices and length, giving proportions (caraṇas; pronounced charanas) of 4:3:2:1 (e.g. Satya: 100% start; Kali: 25% start, 0% end), indicating a de-evolution in spiritual consciousness and an evolution in material consciousness. Kali-yuga is followed by Satya-yuga of the next cycle, where a cycle is called a catur-yuga (pronounced chatur-yuga; a.k.a. mahā-yuga). Each yuga is divided into a main period (a.k.a. yuga proper) and two yuga-sandhis (a.k.a. yuga-sandhyās; connecting periods)—yuga-sandhyā (dawn) and yuga-sandhyāṃśa (a.k.a. yuga-sandhyānśa; dusk)—where each yuga-sandhi lasts for 10% of the main period. Lengths are given in divine years (a.k.a. celestial or Deva years), where a divine year lasts for 360 solar (human) years. A chatur-yuga lasts for 4.32 million solar (12,000 divine) years with 1,728,000 years of Krita-yuga, 1,296,000 years of Treta-yuga, 864,000 years of Dvapara-yuga, and 432,000 years of Kali-yuga.[33][34][35][36][37][f]
Current yuga
[edit]Kali-yuga lasts for 432,000 years and is the 4th of 4 yugas in a cycle as well as the current yuga, with two sandhyas, each lasting for 36,000 years:[g]
- Kali-yuga started 3102 BCE in past:
- = current year + Kali-yuga start year - year zero
- = 2024 + 3102 - 1
- = 5,125 years
- Kali-yuga-sandhya (dawn) ends 32,899 CE in future:
- = Kali-yuga-sandhya - elapsed Kali-yuga
- = 36,000 - (2024 + 3102 - 1)
- = 30,875 years
- Kali-yuga-sandhyamsa (dusk) starts 392,899 CE in future:
- = Kali-yuga - Kali-yuga-sandhyamsa - elapsed Kali-yuga
- = 432,000 - 36,000 - (2024 + 3102 - 1)
- = 390,875 years
- Kali-yuga ends 428,899 CE in future:
- = Kali-yuga - elapsed Kali-yuga
- = 432,000 - (2024 + 3102 - 1)
- = 426,875 years
Current chatur yuga
[edit]A chatur-yuga lasts for 4.32 million years, where the current is the 28th of 71:[g]
- Started 3,891,102 BCE in past:
- = chatur-yuga - Kali-yuga + elapsed Kali-yuga
- = 4,320,000 - 432,000 + (2024 + 3102 - 1)
- = 3,893,125 years
- ≈ 3.89 million years
- Ends 428,899 CE in future:
- = Kali-yuga - elapsed Kali-yuga
- = 432,000 - (2024 + 3102 - 1)
- = 426,875 years

Pitri
[edit]The lifespan of the Pitris (forefathers) lasts for 100 of their years.[19]
- 24 hours (1 day & night) of Pitris = 1 solar month (masa; Moon's two 15-day fortnights: bright and dark)
- 30 days (1 month) of Pitris = 30 solar months (2.5 solar years)
- 12 months (1 year) of Pitris = 30 solar years (1 month of Devas)
- 100 years (lifespan) of Pitris = 3,000 solar years
Deva
[edit]The lifespan of the Devas (gods) lasts for 100 of their years.[19]
- 24 hours (1 day & night) of Devas = 1 solar year (Sun's two 180-day motions: northern and southern)
- 30 days (1 month) of Devas = 30 solar years (1 year of Pitris)
- 12 months (1 year) of Devas = 360 solar years
- 100 years (lifespan) of Devas = 36,000 solar years
Manu
[edit]The lifespan of the Manus (progenitors of mankind) lasts for 100 of their years. Each Manu reigns over a period called a manvantara, each lasting for 71 chatur-yugas (306.72 million years). A total of 14 Manus reign successively in one kalpa (day of Brahma). Preceding the first and following each manvantara is a sandhyā (connection period), each lasting the duration of Satya-yuga (1.728 million years). During each manvantara-sandhyā (a.k.a. manvantara-sandhi), Earth (Bhu-loka) is submerged in water.[27][33][39][40]
- 24 hours (1 day & night) of Manu = 8,520 solar years
- 30 days (1 month) of Manu = 255,600 solar years
- 12 months (1 year) of Manu = 3,067,200 solar years
- 100 years (lifespan) of Manu = 306,720,000 solar years (71 chatur-yugas)
Current manvantara
[edit]A manvantara lasts for 306.72 million years, where the current (ruled by Vaivasvatha Manu) is the 7th of 14:[g]
- Started in past:
- = elapsed 28th chatur-yuga + 27 chatur-yugas
- = chatur-yuga - Kali-yuga + elapsed Kali-yuga + 27 chatur-yugas
- = (4,320,000 - 432,000 + (2024 + 3102 - 1)) + 4,320,000 * 27
- = 120,533,125 years
- ≈ 120.53 million years
- Ends in future:
- = remaining 28th chatur-yuga + 43 chatur-yugas
- = Kali-yuga - elapsed Kali-yuga + 43 chatur-yugas
- = (432,000 - (2024 + 3102 - 1)) + 4,320,000 * 43
- = 186,186,875 years
- ≈ 186.19 million years
Brahma
[edit]The lifespan of Brahma (creator god) lasts for 100 of his years. His 12-hour day or kalpa (a.k.a. day of Brahma) is followed by a 12-hour night or pralaya (a.k.a. night of Brahma) of equal length, each lasting for 4.32 billion years. A kalpa lasts for 1,000 chatur-yugas and has 14 manvantaras and 15 manvantara-sandhyas occurring in it. At the start of Brahma's days, he is re-born and creates the planets and the first living entities. At the end of his days, he and his creations are unmanifest (partial dissolution). His 100-year life (311.04 trillion years) is called a mahā-kalpa, which is followed by a mahā-pralaya (full dissolution) of equal length, where the bases of the universe, prakriti, is manifest at the start and unmanifest at the end of a maha-kalpa. His 100-year life is divided into two 50-year periods, each called a parārdha.[28][40][41] In 100 360-day years (maha-kalpa), there are a total of 36,000 full days: 36,000 kalpas (days proper) and 36,000 pralayas (nights).
- 12 hours (1 day proper: kalpa) of Brahma = 4.32 billion solar years (1,000 chatur-yugas; 14 manvantaras + 15 manvantara-sandhyas)
- 24 hours (1 day & night: kalpa + pralaya) of Brahma = 8.64 billion solar years
- 30 days (1 month) of Brahma = 259.2 billion solar years
- 12 months (1 year) of Brahma = 3.1104 trillion solar years
- 50 years (parardha) of Brahma = 155.52 trillion solar years
- 100 years (lifespan: 2 parardhas) of Brahma = 311.04 trillion solar years
Current kalpa
[edit]A kalpa (day of Brahma, 12 hours) lasts for 4.32 billion years, where the current (Shveta-Varaha Kalpa) is the 1st of 30 in his 1st month of his 51st year:[g]

Hindu texts
[edit]Mahabharata
[edit]The Mahabharata (12.231.12–31) describes units of time from a wink of the eye (nimesha) up to the days (kalpa) and nights (pralaya) of Brahma.[42]
(12–13) The Rishis, measuring time, have given particular names to particular portions. Five and ten winks of the eye make what is called a Kashtha. Thirty Kashthas make what is called a Kala. Thirty Kalas, with the tenth part of a Kala, make a Muhurta. Thirty Muhurtas make up one day and night. Thirty days and nights form a month, and twelve months form a year.
(14) Persons well-read in mathematical science say that a year is made up of two solar motions, viz, the northern and the southern.
(15) The sun makes the day and the night for men. The night is for the sleep of all living creatures and the day is for work.
(16) A month of human beings is equal to a day and night of the departed manes. That division consists in this the light half of the month is their day which is for work, and the dark fortnight is their night for sleep.
(17) A year (of men) is equal to a day and night of the gods. This division consists in this the half year for which the sun travels from the vernal to the autumnal equinox is the day of the gods, and the half year for which the sun moves from the latter to the former is their night.
(18) Calculating by the days and nights of human beings about which I have told you I shall speak of the day and night of Brahman [(Brahma)] and his years also.
(19) I shall, in their order, tell you the number of years that are for different purposes calculated differently, in the Krita, the Treta, the Dwapara, and the Kali yugas.
(20) Four thousand celestial years is the duration of the first or Krita age. The morning of that cycle consists of four hundred years and its evening is of four hundred years.
(21) Regarding the other cycles, the duration of each gradually decreases by a quarter in respect of both the principal period with the minor portion and the conjoining portion itself.
(29) The learned say that these twelve thousand celestial years form what is called a cycle. A thousand such cycles form a single day of Brahman [(Brahma)].
(30) The same is the duration of Brahman's [(Brahma's)] night. With the beginning of Brahman's [(Brahma's)] day the universe begins to come into being. During the period of universal dissolution the Creator sleeps in Yoga meditation. When the period of sleep expires, He awakes.
(31) What is Brahman's [(Brahma's)] day covers a thousand such cycles. His night also covers a thousand similar cycles. They who know this are said to know the day and the night.
— Mahabharata, Book 12 (Shanti Parva), Ch. 231[42][i]
Manusmriti
[edit]The Manusmriti (a.k.a. Laws of Manu; 1.64–80) describes units of time from a twinkling of the eye (nimesha) up to the days (kalpa) and nights (pralaya) of Brahma.[43][44][45]
निमेषा दश चाष्टौ च काष्ठा त्रिंशत् तु ताः कला ।
त्रिंशत् कला मुहूर्तः स्यादहोरात्रं तु तावतः ॥ ६४ ॥
nimeṣā daśa cāṣṭau ca kāṣṭhā triṃśat tu tāḥ kalā ।
triṃśat kalā muhūrtaḥ syādahorātraṃ tu tāvataḥ ॥ 64 ॥
(64) Eighteen nimeshas (twinklings of the eye, are one kashtha), thirty kashthas one kala, thirty kalas one muhurta, and as many (muhurtas) one day and night.अहोरात्रे विभजते सूर्यो मानुषदैविके ।
रात्रिः स्वप्नाय भूतानां चेष्टायै कर्मणामहः ॥ ६५ ॥
ahorātre vibhajate sūryo mānuṣadaivike ।
rātriḥ svapnāya bhūtānāṃ ceṣṭāyai karmaṇāmahaḥ ॥ 65 ॥
(65) The sun divides days and nights, both human and divine, the night (being intended) for the repose of created beings and the day for exertion.पित्र्ये रात्र्यहनी मासः प्रविभागस्तु पक्षयोः ।
कर्मचेष्टास्वहः कृष्णः शुक्लः स्वप्नाय शर्वरी ॥ ६६ ॥
pitrye rātryahanī māsaḥ pravibhāgastu pakṣayoḥ ।
karmaceṣṭāsvahaḥ kṛṣṇaḥ śuklaḥ svapnāya śarvarī ॥ 66 ॥
(66) A month is a day and night of the manes, but the division is according to fortnights. The dark (fortnight) is their day for active exertion, the bright (fortnight) their night for sleep.दैवे रात्र्यहनी वर्षं प्रविभागस्तयोः पुनः ।
अहस्तत्रोदगयनं रात्रिः स्याद् दक्षिणायनम् ॥ ६७ ॥
daive rātryahanī varṣaṃ pravibhāgastayoḥ punaḥ ।
ahastatrodagayanaṃ rātriḥ syād dakṣiṇāyanam ॥ 67 ॥
(67) A year is a day and a night of the gods; their division is (as follows): the half year during which the sun progresses to the north will be the day, that during which it goes southwards the night.ब्राह्मस्य तु क्षपाहस्य यत् प्रमाणं समासतः ।
एकैकशो युगानां तु क्रमशस्तन्निबोधत ॥ ६८ ॥
brāhmasya tu kṣapāhasya yat pramāṇaṃ samāsataḥ ।
ekaikaśo yugānāṃ tu kramaśastannibodhata ॥ 68 ॥
(68) But hear now the brief (description of) the duration of a night and a day of Brahman [(Brahma)] and of the several ages (of the world, yuga) according to their order.चत्वार्याहुः सहस्राणि वर्षाणां तत् कृतं युगम् ।
तस्य तावत्शती सन्ध्या सन्ध्यांशश्च तथाविधः ॥ ६९ ॥
catvāryāhuḥ sahasrāṇi varṣāṇāṃ tat kṛtaṃ yugam ।
tasya tāvatśatī sandhyā sandhyāṃśaśca tathāvidhaḥ ॥ 69 ॥
(69) They declare that the Krita age (consists of) four thousand years (of the gods); the twilight preceding it consists of as many hundreds, and the twilight following it of the same number.इतरेषु ससन्ध्येषु ससन्ध्यांशेषु च त्रिषु ।
एकापायेन वर्तन्ते सहस्राणि शतानि च ॥ ७० ॥
itareṣu sasandhyeṣu sasandhyāṃśeṣu ca triṣu ।
ekāpāyena vartante sahasrāṇi śatāni ca ॥ 70 ॥
(70) In the other three ages with their twilights preceding and following, the thousands and hundreds are diminished by one (in each).यदेतत् परिसङ्ख्यातमादावेव चतुर्युगम् ।
एतद् द्वादशसाहस्रं देवानां युगमुच्यते ॥ ७१ ॥
yadetat parisaṅkhyātamādāveva caturyugam ।
etad dvādaśasāhasraṃ devānāṃ yugamucyate ॥ 71 ॥
(71) These twelve thousand (years) which thus have been just mentioned as the total of four (human) ages, are called one age of the gods.दैविकानां युगानां तु सहस्रं परिसङ्ख्यया ।
ब्राह्ममेकमहर्ज्ञेयं तावतीं रात्रिमेव च ॥ ७२ ॥
daivikānāṃ yugānāṃ tu sahasraṃ parisaṅkhyayā ।
brāhmamekamaharjñeyaṃ tāvatīṃ rātrimeva ca ॥ 72 ॥
(72) But know that the sum of one thousand ages of the gods (makes) one day of Brahman [(Brahma)], and that his night has the same length.तद् वै युगसहस्रान्तं ब्राह्मं पुण्यमहर्विदुः ।
रात्रिं च तावतीमेव तेऽहोरात्रविदो जनाः ॥ ७३ ॥
tad vai yugasahasrāntaṃ brāhmaṃ puṇyamaharviduḥ ।
rātriṃ ca tāvatīmeva te'horātravido janāḥ ॥ 73 ॥
(73) Those (only, who) know that the holy day of Brahman [(Brahma)], indeed, ends after (the completion of) one thousand ages (of the gods) and that his night lasts as long, (are really) men acquainted with (the length of) days and nights.यद् प्राग् द्वादशसाहस्रमुदितं दैविकं युगम् ।
तदेकसप्ततिगुणं मन्वन्तरमिहोच्यते ॥ ७९ ॥
yad prāg dvādaśasāhasramuditaṃ daivikaṃ yugam ।
tadekasaptatiguṇaṃ manvantaramihocyate ॥ 79 ॥
(79) The before-mentioned age of the gods, (or) twelve thousand (of their years), being multiplied by seventy-one, (constitutes what) is here named the period of a Manu (Manvantara).मन्वन्तराण्यसङ्ख्यानि सर्गः संहार एव च ।
क्रीडन्निवैतत् कुरुते परमेष्ठी पुनः पुनः ॥ ८० ॥
manvantarāṇyasaṅkhyāni sargaḥ saṃhāra eva ca ।
krīḍannivaitat kurute parameṣṭhī punaḥ punaḥ ॥ 80 ॥
(80) The Manvantaras, the creations and destructions (of the world, are) numberless; sporting, as it were, Brahman [(Brahma)] repeats this again and again.
— Manusmriti, Ch. 1[44]
According to Patrick Olivelle, most scholars take the table of contents (1.111–118) to be an addition, but for him the account of time and cosmology (1.61–86) to the aforementioned (1.118) are out of place redactions. He feels the narrative should have ended when the initial command to "listen" (1.4) was repeated (1.60), then transition to "learn" (2.1).[46]
Georg Bühler, whose translation has remained the standard for over a century according to Olivelle, translated 1.71 as 12,000 years in a four-aged period, same as Sir William Jones's translation, both based on Kulluka Bhatta's commentary. Medhatithi translated it as 12,000 four-aged periods in an age of the gods. Kulluka and Olivelle reject Medhatithi's interpretation based on 1.79 mentioning 12,000 without a qualifier ("etat" or "this") and must be assumed as years.[47]
Surya Siddhanta
[edit]The Surya Siddhanta (1.10–21) describes units of time from a respiration (prana)[48] up to the 100-year lifespan of Brahma (maha-kalpa).[49]
lokānām antakṛt kālaḥ kālo 'nyaḥ kalanātmakaḥ ।
sa dvidhā sthūlasūkṣmatvān mūrtaś cāmūrta ucyate ॥ 10 ॥
(10) Time is the destroyer of the worlds; another Time has for its nature to bring to pass. This latter, according as it is gross or minute, is called by two names, real (murta) and unreal (amurta).prāṇādiḥ kathito mūrtas truṭyādyo 'mūrtasaṃjñakaḥ ।
ṣaḍbhiḥ prāṇair vināḍī syāt tatṣaṣṭyā nāḍikā smṛtā ॥ 11 ॥
(11) That which begins with respirations (prana) is called real; that which begins with atoms (truti) is called unreal. Six respirations make a vinadi, sixty of these a nadi;nāḍīṣaṣṭyā tu nākṣatram ahorātraṃ prakīrtitam ।
tattriṃśatā bhaven māsaḥ sāvano 'rkodayais tathā ॥ 12 ॥
(12) And sixty nadis make a sidereal day and night. Of thirty of these sidereal days is composed a month; a civil (savana) month consists of as many sunrises;aindavas tithibhis tadvat saṃkrāntyā saura ucyate ।
māsair dvādaśabhir varṣaṃ divyaṃ tad aha ucyate ॥ 13 ॥
(13) A lunar month, of as many lunar days (tithi); a solar (saura) month is determined by the entrance of the sun into a sign of the zodiac : twelve months make a year. This is called a day of the gods.surāsurāṇām anyonyam ahorātraṃ viparyayāt ।
tatṣaṣṭiḥ ṣaḍguṇā divyaṃ varṣam āsuram eva ca ॥ 14 ॥
(14) The day and night of the gods and of the demons are mutually opposed to one another. Six times sixty [360] of them are a year of the gods, and likewise of the demons.taddvādaśasahasrāṇi caturyugam udāhṛtam ।
sūryābdasaṃkhyayā dvitrisāgarair ayutāhataiḥ ॥ 15 ॥
(15) Twelve thousand of these divine years are denominated a Quadruple Age (caturyuga); of ten thousand times four hundred and thirty-two [4,320,000] solar yearssaṃdhyāsaṃdhyāṃśasahitaṃ vijñeyaṃ tac caturyugam ।
kṛtādīnāṃ vyavastheyaṃ dharmapādavyavasthayā ॥ 16 ॥
(16) Is composed that Quadruple Age, with its dawn and twilight. The difference of the Golden and the other Ages, as measured by the difference in the number of the feet of Virtue in each, is as follows:yugasya daśamo bhāgaś catustridvyekasaṃguṇaḥ ।
kramāt kṛtayugādīnāṃ ṣaṣṭhāṃśaḥ saṃdhyayoḥ svakaḥ ॥ 17 ॥
(17) The tenth part of an Age, multiplied successively by four, three, two, and one, gives the length of the Golden and the other Ages, in order : the sixth part of each belongs to its dawn and twilight.yugānāṃ saptatiḥ saikā manvantaram ihocyate ।
kṛtābdasaṃkhyās tasyānte saṃdhiḥ prokto jalaplavaḥ ॥ 18 ॥
(18) One and seventy [71] Ages are styled here a Patriarchate (manvantara); at its end is said to be a twilight which has the number of years of a Golden Age, and which is a deluge.sasaṃdhayas te manavaḥ kalpe jñeyāś caturdaśa ।
kṛtapramāṇaḥ kalpādau saṃdhiḥ pañcadaśaḥ smṛtaḥ ॥ 19 ॥
(19) In an Æon (kalpa) are reckoned fourteen such Patriarchs (manu) with their respective twilights; at the commencement of the Æon is a fifteenth dawn, having the length of a Golden Age.ittham yugasahasreṇa bhūtasaṃhārakārakaḥ ।
kalpo brāhmam ahaḥ proktaṃ śarvarī tasya tāvatī ॥ 20 ॥
(20) The Æon, thus composed of a thousand Ages, and which brings about the destruction of all that exists, is styled a day of Brahma; his night is of the same length.paramāyuḥ śataṃ tasya tayāhorātrasaṃkhyayā ।
āyuṣo 'rdhamitaṃ tasya śeṣakalpo 'yam ādimaḥ ॥ 21 ॥
(21) His extreme age is a hundred, according to this valuation of a day and a night ...

Each manvantara is preceded and followed by a period of 1,728,000 (= 4K) years when the entire earthly universe (bhu-loka) will submerge under water. The period of this deluge is known as manvantara-sandhya (sandhya meaning, twilight). ... According to the traditional time-keeping ... Thus in Brahma's calendar the present time may be coded as his 51st year - first month - first day - 7th manvantara - 28th maha-yuga - 4th yuga or kaliyuga.

* HINDUISM: Myths of time and eternity: ... Each yuga is preceded by an intermediate "dawn" and "dusk." The Krita yuga lasts 4,000 god-years, with a dawn and dusk of 400 god-years each, or a total of 4,800 god-years; Treta a total of 3,600 god-years; Dvapara 2,400 god-years; and Kali (the current yuga) 1,200 god-years. A mahayuga thus lasts 12,000 god-years ... Since each god-year lasts 360 human years, a mahayuga is 4,320,000 years long in human time. Two thousand mahayugas form one kalpa (eon) [and pralaya], which is itself but one day in the life of Brahma, whose full life lasts 100 years; the present is the midpoint of his life. Each kalpa is followed by an equally long period of abeyance (pralaya), in which the universe is asleep. Seemingly the universe will come to an end at the end of Brahma's life, but Brahmas too are innumerable, and a new universe is reborn with each new Brahma.
* YUGA: Each yuga is progressively shorter than the preceding one, corresponding to a decline in the moral and physical state of humanity. Four such yugas ... make up a mahayuga ("great yuga") ... The first yuga (Krita) was an age of perfection, lasting 1,728,000 years. The fourth and most degenerate yuga (Kali) began in 3102 BCE and will last 432,000 years. At the close of the Kali yuga, the world will be destroyed by fire and flood, to be re-created as the cycle resumes. In a partially competing vision of time, Vishnu's 10th and final Avatar, Kalki, is described as bringing the present cosmic cycle to a close by destroying the evil forces that rule the Kali yuga and ushering in an immediate return to the idyllic Krita yuga. - ^ Hans Kng (31 October 2006).

(19) The duration of the Satya millennium equals 4,800 years of the years of the demigods; the duration of the Tretā millennium equals 3,600 years of the demigods; the duration of the Dvāpara millennium equals 2,400 years; and that of the Kali millennium is 1,200 years of the demigods. PURPORT: As aforementioned, one year of the demigods is equal to 360 years of the human beings. The duration of the Satya-yuga is therefore 4,800 × 360, or 1,728,000 years. The duration of the Tretā-yuga is 3,600 × 360, or 1,296,000 years. The duration of the Dvāpara-yuga is 2,400 × 360, or 864,000 years. And the last, the Kali-yuga, is 1,200 × 360, or 432,000 years. - ^ Burgess 1935, p. ix (Introduction): Calculated date of 2163102 B.C. for "the end of the Golden Age (Krta yuga)", the start of Treta yuga, mentioned in Surya Siddhanta 1.57.

a day in the life of Brahma is divided into 14 periods called manvantaras ("Manu intervals"), each of which lasts for 306,720,000 years. In every second cycle [(new kalpa after pralaya)] the world is recreated, and a new Manu appears to become the father of the next human race. The present age is considered to be the seventh Manu cycle.
