According to the astronomer and mathematician
Aryabhatta the Kali Yuga started in 3102 BCE. He finished his book “Aryabhattiya” in 499 CE, in which he gives the exact year of the beginning of Kali Yuga. He writes that he wrote the book in the "year 3600 of the Kali Age" at the age of 23. As it was the 3600th year of the Kali Age when he was 23 years old, and given that Aryabhatta was born in 476 CE, the beginning of the Kali Yuga would come to (3600 - (476 + 23) + 1 (As only one year elapses between 1 BCE and 1 CE) = ) 3102 BCE.
According to KD Abhyankar, the starting point of Kaliyuga is an extremely rare planetary alignment, which is depicted in the
 Going by this alignment the year 3102 BCE is slightly off. The actual date for this alignment is February 7 of 3104 BCE. There is also sufficient proof to believe that Vrdhha
Garga knew of
precession at least by 500 BCE. Garga had calculated the rate of precession to within 30% of what the modern scholars estimate.
Most interpreters of vedic scriptures, as
Goswami and his recent disciple
Bhaktivedanta Swami Prabhupada believe that Earth is currently in Kali Yuga and lasts 432,000 years. Other authors, such as
Swami Sri Yukteswar
 believe that it is now an ascending Dvapara Yuga, indicating levels of cycles within each major Yuga period as each being a development, the smaller cycles within cycles eventually leading to full development of the qualities of the ages. The Kali Yuga is thought by some authors to last 6480 years although other durations have been proposed.
