Brahma's Age - Astonishing

        A Kalpa is day of Brahma and one day of Brahma consists of a thousand cycles of four yugas, or ages: Satya, Treta, Dvapara and Kali. The cycle of Satya is charaterized by virtue, wisdom and religion, there being pratically no ignorance and vice, and the yuga lasts 1,728,000 years. In the Treta-yuga vice is introduced, and this yuga lasts 1,296,000 years. In the Dvapara-yuga there is an even greater decline in virtue and religion, vice increasing, and this yuga lasts 864,000 years. And finally in Kali-yuga (the yuga we have now been experiencing over the past 5000 years) there is an abundance of strife, ignorance, religion, vice, true virtue being practically nonexistent, and this yuga lasts 432,000 years. In Kali-yuga vice increases to such a point that termination of yuga happens by incarnated form of Supreme Lord himself and he commences another Satya-yuga. Then the process is set rolling again. These four yugas, rotating a thousand times, comprise one day of Brahma, and the same number comprise one night. Brahma lives one hundred of such years and then dies.

We can calculate the age of the earth from the age of Brahma. The Vedic chronology of Hinduism uses a base unit of calculation called a chaturyugi. This is comprised of 4 yugas (periods of time). Their lengths and corresponding names are:

1,728,000 years = sat yuga

1,296,000 = treta yuga

864,000 = dwapar yuga

432,000 = kali yuga

---

4,320,000 years = one charturyugi (one 4-yuga cycle)

---

1000 chaturyugis = one day of Brahma

1000 chaturyugis = one night of Brahma

8,640,000,000 years = one full day (24 hours) of Brahma

100 celestial years = age that Brahma lives to

50 celestial years = Brahma's current age, or,

155.5 trillion years = the current age of this earth
