Hindu units of time

Vedic and Puranic texts describe units of Kala measurements, from Paramaṇu (about 17 microseconds) to Maha-Manvantara (311.04 trillion years). According to these texts, the creation and destruction of the universe is a cyclic process, which repeats itself forever. Each cycle starts with the birth and expansion (lifetime) of the universe equaling 311.04 trillion years, followed by its complete annihilation (which also prevails for the same duration). The current Universe is, according to Hindu scripture, in the 51st year of Brahma, which suggests that it was created about 155.5 trillion years ago. This figure does not match the modern estimated age of the universe of ≈ 13.79 billion years.

Time units

Hindu measurements in logarithmic scale (approx.).

Various units of time are used across the Vedas, Puranas, Mahabharata, Suryasidhanta etc. Especially, Nimesha's multiple, it varies to 3, 10, 15, 18, 20, 27, 30, 45, 48, 60. At the lower end, these are pretty consistent. The Complete Hindu metrics of time (Kāla Vyavahāra) can be summarised as below.

Reckoning of time among other entities

Among the Pitá¹›s (forefather)

Among the Devas

The life span of any Hindu deva spans nearly (or more than) 4.5 million years. Statistically, we can also look it as:

The Viṣṇu Purāṇa Time measurement section of the Viṣṇu Purāṇa Book I Chapter III explains the above as follows:

For Brahma

(2 Kalpas constitute a day and night of Brahma, 8.64 billion human years)

One day of Brahma is divided into 1000 parts called charaṇas. The charaṇas are divided as follows:

The Four Yugas
4 charaṇas (1,728,000 solar years) Satya Yuga
3 charaṇas (1,296,000 solar years) Treta Yuga
2 charaṇas (864,000 solar years) Dvapara Yuga
1 charaṇas (432,000 solar years) Kali Yuga
Source:

The cycle repeats itself, so altogether there are 1,000 cycles of Mahā-Yuga in one day of Brahma.

  • One cycle of the above four Yugas is one Mahā-Yuga (4.32 million solar years)
  • as is confirmed by the GÄ«tā Åšloka 8.17 (statement) "sahasra-yuga-paryantam ahar yad brahmaṇo viduḥ rātriṁ yuga-sahasrāntāṁ te 'ho-rātra-vido janāḥ", meaning, a day of brahma is of 1000 Mahā-Yuga. Thus a day of Brahma, Kalpa, is of duration: 4.32 billion solar years. Two Kalpas constitute a day and night (Adhi Sandhi) of Brahma.
  • A Manvantara consists of 71 Mahā-Yuga (306,720,000 solar years). Each Manvantara is ruled by a Manu.
  • After each Manvantara follows one Saṃdhi Kāla of the same duration as a Ká¹›ta Yuga (1,728,000 = 4 Charaṇas). (It is said that during a Saṃdhi Kāla, the entire earth is submerged in water.)
  • A Kalpa consists of a period of 4.32 Billion solar years followed by 14 Manvataras and Saṃdhi Kalas.
  • A day of Brahma equals
(14 times 71 Mahā-Yuga) + (15 × 4 Charaṇas)
= 994 Mahā-Yuga + (15 * 4800)
= 994 Mahā-Yuga + (72,000 years)[deva years] / 6 = 12,000[deva years] viz. one maha yuga.
= 994 Mahā-Yuga + 6 Mahā-Yuga
= 1,000 Mahā-Yuga

The Surya Siddhanta definition of timescales

The Surya Siddhanta [Chapter 14 Mānādhyāyah (मानाध्यायः)], documents a comprehensive model of nine divisions of time called māna (मान) which span from very small time units (Prāņa [प्राण] - 4 seconds) to very large time scales (Para [पर] - 311.04 Trillion solar years).

The current date

Currently, 50 years of Brahma have elapsed. The last Kalpa at the end of 50th year is called Padma Kalpa. We are currently in the first 'day' of the 51st year.[4] This Brahma's day, Kalpa, is named as Shveta-Varaha Kalpa. Within this Day, six Manvantaras have already elapsed[5] and this is the seventh Manvantara, named as – Vaivasvatha Manvantara (or Sraddhadeva Manvantara). Within the Vaivasvatha Manvantara, 27 Mahayugas[5] (4 Yugas together is a Mahayuga), and the Krita,[6] Treta and Dwapara Yugas of the 28th Mahayuga have elapsed. This Kaliyuga is in the 28th Mahayuga. This Kaliyuga began in the year 3102 BCE in the proleptic Julian Calendar.[7] Since 50 years of Brahma have already elapsed, this is the second Parardha, also called as Dvithiya Parardha.

The time elapsed since the current Brahma has taken over the task of creation can be calculated as

432000 × 10 × 1000 × 2 = 8.64 billion years (2 Kalpa (day and night) )

8.64 × 109 × 30 × 12 = 3.1104 Trillion Years (1 year of Brahma)
3.1104 × 1012 × 50 = 155.52 Trillion Years (50 years of Brahma)

(6 × 71 × 4320000 ) + 7 × 1.728 × 10^6 = 1852416000 years elapsed in first six Manvataras, and Sandhi Kalas in the current Kalpa

27 × 4320000 = 116640000 years elapsed in first 27 Mahayugas of the current Manvantara

1.728 × 10^6 + 1.296 × 10^6 + 864000 = 3888000 years elapsed in current Mahayuga

3102 + 2016 = 5118 years elapsed in current Kaliyuga.

So the total time elapsed since current Brahma is

155520000000000 + 1852416000 + 116640000 + 3888000 + 5115 = 155,521,972,949,117 years (one hundred fifty-five trillion, five hundred twenty-one billion, nine hundred seventy-two million, nine hundred forty-nine thousand, one hundred seventeen years) as of 2016 AD

The current Kali Yuga began at midnight 17 February / 18 February in 3102 BCE in the proleptic Julian calendar.[8] As per the information above about Yuga periods, only 5,117 years are passed out of 432,000 years of current Kali Yuga, and hence another 426,883 years are left to complete this 28th Kali Yuga of Vaivaswatha Manvantara.
