A Yuga lasts 1,000Â years and ten Yugas together equal to 4,320,000Â years make one Kalpa. The name of the present Yuga is taken from the Hindu epic Mahabharata, which states that it will last 100Â years. The present Kali Yuga is called Dvapara-Yuga ('the age of two rivers'). The present 'Kali Yuga' cycle started about 2,465 years ago when the Guheswari Ishwari calendar was in use, and it will end when the Surya Siddhanta calendar is started. A year in a Yuga is called 'Krita', 'Treta', 'Dvapara', or 'Kali'. A complete Yuga occurs when one cycle of time coincides with one half the total duration of a Kalpa, lasting approximately 306 trillion 40 million earth years. In Hindu religion and mythology, a 'Yuga' denotes an age or an epoch. Jain philosophy divides the time from the beginning of the universe to its end into a similar number of Yugas. The Yuga cycle, which is hundreds of millions of years long, is divided into Yugas. The calendar system itself is based on a 10-year intercalary cycle called Panchanga. The dates for each season are determined based on astronomical observations and calculations. The cycles of time are called Pancha Yuga and consist of six seasons, known as Ritui which proceed according to 19-year long cycles. It is used in the Indian State of Odisha as well as by the Bengali community in Bangladesh. The Oriya Calendar is a lunisolar calendar that regulates the Hindu year.
