Kalī Yuga (lit. Age of Kali, also known as The Age of Darkness), is one of the four stages of development that the world goes through as part of the cycle of Yugas, as described in Hindu scriptures, the others being Dwapara Yuga, Treta Yuga, and Satya Yuga.
Kali Yuga ("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 apocalyptic demon Kali (who is not to be confused with the goddess Kālī). The "Kali" of Kali Yuga means "strife", "discord", "quarrel" or "contention".
