18 winks of the eye= 1 Kastha
30 kastas...........=1 Kala
30 kalas ...........=1 Muhurta
30 muhurtas.........=1 Day and night.(This Ahoratree is the human day.)

According to Jyotisha.
6 respirations.............= 1 Vighati
60 Vighatikas .............= 1 Ghatika
60 Ghatikas ...............= 1 Day and night(This Ahoratree is the human day.)

15 days...........= 1 Paksha
2 pakshas.........= 1 human month

1 human month = 1 day and night: of the Pitris(Manes),the Sukla Paksha being their day and the Krishna Paksha being their night.

12 Human months or one year = 1 The Ahoratree of the Devas

Ashadha to Margasira is night of the Devatas.

30 human years = 1 Month of the Devatas.
360 human years or 12 Daiva months = 1 Year of the Devatas

12000 Daiva years or 43,20,000 Years = One Daiva yuga or ordinary Mahayuga

0.4 Mahayuga = 4800 Daiva years = 17,28,000 years = Kritayuga with yugasandi and Sandhyamsa.
0.3 Mahayuga = 3600 Daiva Years = 12,96,000 years = Tretayuga
0.2 Mahayuga = 2400 Daiva Years = 8,64,000 years = Dwaparayuga
0.1 Mahayuga = 1200 Daiva Years = 4,32,000 years = Kaliyuga

1 Mahayuga = Kritayuga + Tretayuga + Dwaparayuga + Kaliyuga

1000 Daiva Yugas or ordinary Maha Yugas or 432 crores of ordinary years = One day time for Brahma. This is Udayakalpa. = 30 Ghaticas for Brahma.

Another 1000 Daiva Yugas or 432 crores of ordinary years = Night for Brahma or Kshaya kalpa

During the day time of Brahma(1000 Mahayugas) , 14 Manus look after this world. Each Manu reigns 71 Mahayugas . In the first day of the fifty first year of Brahma have rolled away the following periods:-
6 Manus = 6 x 71 = 426 Mahayugas = 184,03,20,000
27 Mahayugas of the period of Vivasvata, the seventh Manu = 11,66,40,000
The Kritayuga of the 28th Mahayuga = 0.4 Mahayuga = 17,28,000
The Tretayuga = 00.3 Mahayuga = 12,96,000
The Dwapara = 0.2 Mahayuga = 8,64,000

Total.= 426+27+0.9 Mahayugas + 5056 years = 196,08,53,056 years

Seven Jalapralayas each of duration of a Kritayuga
= 7*0.4 Mahayugas =2.8 Mahayugas = 7 * 17,28,000 = 1,20,96,000

Thus we arrive at this conclusion :- Brahma has completed his fiftieth year; and in the first day of his fifty first year of life have gone by thirteen (Brahma)ghatikas, and forty-two vighatikas i. e., 195,58,85,056 years upto 1955 A. D. This is recorded in our Panchangas year by year.
This is Genuine Historical Data of the Vedas.
In conformity of the above Vedic Historical Data. for the modern history of Bharat, we can safely adopt the Puranic data commencing from the Mahabharata war of 3138 B. C. or 36 years
before the beginning of Kali Yoga 3102 B. C., or 62 years before the Saptarshi era of 3076 B.C.
