  The start date and time of Kali Yuga was at midnight (00:00) on 17/18 February 3102 BCE.
  
  Astronomer and mathematician Aryabhata, who was born in 476 CE, finished his book Aryabhatiya in 499 CE, in which he wrote "When the three yugas (satyug, tretayug and dwaparyug) have elapsed and 60 x 60 (3,600) years of kaliyug have already passed, I am now 23 years old." Based on this information, Kali Yuga began in 3102 BCE, which is calculated from 3600 - (476 + 23) + 1 (no year zero from 1 BCE to 1 CE).
  
  According to K. D. Abhyankar, the starting point of Kali Yuga is an extremely rare planetary alignment, which is depicted in the Mohenjo-daro seals.
