Kali Yuga (Kali-Yuga) (Sanskrit: कली युग, according to various interpretations, the era of the goddess Kali or the demon Kali) is the last era (yuga) in Hinduism, after which the renewal of time begins.
Kali Yuga is characterized by moral decline. Various datings of Kali Yuga are given in Indian literature. According to the Puranas, the Kali Yuga began before Sri Krishna's return to Vaikuntha at midnight on January 23 Gregorian or February 18 Julian 3102 BC. e. (if counted without a zero year) 35 years after the battle of Mahabharata and lasts for 1200 deva years. The last Kaliyuga refers to the 28th chaturyuga of the 7th manvantara of Vaivasvata Manu.
The 12th Canto of the SB says that astronomically the Kali Yuga came just before Krishna's return to Vaikuntha, but His presence on earth prevented Kali from manifesting, and when He left, she fully manifested. In the Mahabharata, Krishna says that a new yuga will begin after the death of Bhishma's grandfather, i.e. December 10 -3138 (Julian. January 5, 3136 BC)
Bhagavata Purana 12.2.
Of the seven stars that make up the constellation of the Seven Wise Men, Pulaha and Kratu are the first to rise in the night sky. It is said that the lunar house, through which the celestial meridian connecting north and south will pass through these stars, will rule the constellation of the Seven Sages at this time. The Seven Sages will remain bound to this lunar home for one hundred human years. During your lifetime, O king, they settled in the Nakshatra called Magha.
When the constellation of the seven sages passes through the lunar house of Magha, the age of Kali begins. It lasts for twelve hundred deva years.
When the great sages of the Saptarisha constellation move from Magha to Purvashadha, Kali will enter into full force, beginning with the dynasty of King Nanda. Kratu is named after Dubhe, the second brightest star in the Saptarisha mandala or the Big Dipper asterism in the Ursa Major constellation. , Pulaha — Merak. With the help of an imaginary line passing through the stars Dubhe (α UMa / α Ursae Majoris) and Merak (Beta Ursae Majoris (β UMa / β Ursae Majoris), the North Star can be found. The Saptarishi nakshatra calendar was used to date long periods of time.
After a thousand celestial years of the Kali Yuga, the Satya Yuga will appear again. Until then, the minds of all people will be clear
