Kali Yuga ( Devanāgarī: , lit. "age of [the demon] Kali", or "age of vice") is the last of the four stages the world goes through as part of the cycle of yugas described in the Sanskrit scriptures, within the present Mahayuga. The other ages are called Satya Yuga, Treta Yuga, and Dvapara Yuga.
Kali Yuga is associated with the demon Kali (not to be confused with the goddess Kālī). The "Kali" of Kali Yuga means "strife", "discord", "quarrel" or "contention".
According to Puranic sources, Krishna's departure marks the end of Dvapara Yuga and the start of Kali Yuga, which is dated to 17/18 February 3102 BCE.
