The Hindu Age is a period of time in Indian history that is divided into four distinct eras, known as Yugas. The four Yugas are Satya Yuga, Treta Yuga, Dvapara Yuga, and Kali Yuga. Each Yuga is associated with a different set of values and beliefs, and the transition from one Yuga to the next is marked by a gradual decline in spiritual and moral values. The Hindu Age is believed to have begun with the Satya Yuga, which is said to have lasted for 1, 728, 000 years.
