The shortest period of time is a Matra, which is equal to the twinkling of the human eye. Fifteen Matras = one Kashtha;
thirty Kashthas = one Kala;
fifteen Kalas = one Nadika.
A Nadika is ascertained by a measure of water, with a vessel made of twelve Palas and a half of copper, in the bottom of which there is to be a hole made with a tube of gold, of the weight of four Mashas, and four inches long. According to the Magadha measure, the vessel should hold a Prastha (or sixteen Palas) of water.
Two of these Nadis = one Muhurtta;
thirty Muhurtta = one day and night.
Thirty such periods = one month;
twelve months = one year, or a day and night of the gods;
three hundred and sixty such days = one year of the celestials.
An aggregate of four ages contains twelve thousand divine years; and a thousand periods of four ages complete a day of Brahma.
That period is also termed a Kalpa, during which fourteen Manus preside; and at the end of it occurs the incidental or Brahma dissolution.

Krita Yuga = 4000 + Sandhya 400 + Sandhyansa 400 = 4800
Treta Yuga = 3000 + Sandhya 300 + Sandhyansa 300 = 3600

Kali Yuga = 1000 + Sandhya 100 + Sandhyansa 100 = 1200
Total = 12000.
one hundred years of Brahma, are 311.040.000.000.000 years of mortals.
