## 23 Sep Measurement of Time

The Indian time measurement system is considered to be the oldest time measurement systems. Indian scriptures give us a wealth of information about the different methods and techniques used in ancient India for time measurement. This measurement system is not only complete but also very precise and accurate.
In Surya Siddhanta, Bhaskaracharya calculates the time taken for the earth to orbit the sun to 9 decimal places.
Modern accepted measurement = 365.2596 days.
Between Bhaskaracharya’s ancient measurement 1500 years ago and the modern measurement, the difference is only 0.00085 days, only 0.0002%.
34000TH of a Second to 4.32 Billion Years
India has given the idea of the smallest and the largest measure of time.
Krati Krati = 34,000th of a second
1 Truti = 300th of a second
2 Truti = 1 Luv
2 Luv = 1 Kshana
30 Kshana = 1 Vipal
60 Vipal = 1 Pal
60 Pal = 1 Ghadi (24 minutes)
2.5 Gadhi = 1 Hora (1 hour)
24 Hora = 1 Divas (1 day)
7 Divas = 1 saptaah (1 week)
4 Saptaah = 1 Maas (1 month)
2 Maas = 1 Rutu (1 season)
6 Rutu = 1 Varsh (1 year)
100 Varsh = 1 Shataabda (1 century)
10 Shataabda = 1 sahasraabda
432 Sahasraabda = 1 Yug (Kaliyug)
2 Yug = 1 Dwaaparyug
3 Yug = 1 Tretaayug
4 Yug = 1 Krutayug
10 Yug = 1 Mahaayug (4,320,000 years)
1000 Mahaayug = 1 Kalpa
1 Kalpa = 4.32 billion years
As is confirmed by the Gita statement “sahasra-yuga paryantam ahar-yad brahmano viduH”, meaning, a day of brahma is of 1000 (maha-)yugas. Thus a day of Brahma, kalpa, is of duration: 4.32 billion solar years. Two kalpas constitute a day and night of Brahma
30 days of Brahma = 1 month of Brahma (259,200,000,000 human years)
12 months of Brahma = 1 year of Brahma (3,110,400,000,000 human years)
25 years of Brahma = 1 kalpa (77,760,000,000,000 human years)
2 kalpas = 1 parardha (155,520,000,000,000 human years)
2 parardhas = 100 years of Brahma, the lifespan of Brahma (311,040,000,000,000 human years)
The Vishnu Purana Time measurement section of the Vishnu Purana Book I Chapter III explains the above as follows:
360 days of the gods = 1 year of the gods
12,000 years of the gods = 4 Yugas
1,000 sets of 4 Yugas = a day of Brahmá
50 years of Brahma = 1 Pararddham
100 years of Brahma = 1 Param
4,000 + 400 + 400 = 4,800 years = 1 Krita Yuga
3,000 + 300 + 300 = 3,600 years = 1 Tretá Yuga
2,000 + 200 + 200 = 2,400 years = 1 Dwápara Yuga
1,000 + 100 + 100 = 1,200 years = 1 Kali Yuga
Alternately, the reigns of 7 Rishis, Indra and Manu = 1 Manwantara = 71×12,000+A (A is not given) = 852,000 years of the gods+A (A is not given)
14 Manwantaras = a day of Brahmá
We are currently in the 28th kaliyuga of the first day of the 1st year of the shvetavaraha kalpa of the second parardha of Brahma in the reign of the 7th Manu, Manu Vaivasvata. This is the 51st year of the present Brahma and so about 155 trillion years have elapsed since He took over as Brahma.
The current Kali Yuga (Iron Age) began at midnight 17 February / 18 February in 3102 BC in the proleptic Julian calendar.
