• The current Kali Yuga began at midnight 17 February / 18 February in 3102 BC in the proleptic Julian calendar.

3102 + 2009 = 5112 years elapsed in current Kaliyuga. This Kaliyuga began in the year 3102 BC in the proleptic Julian Calendar. More information on Hindu asronomical and scientific time calculations of history based on Vedas:

• Gītā was spoken at least 120,400,000 years ago; and in human society it has been extant for two million years. It was respoken by the Lord again to Arjuna about five thousand years ago. That is the rough estimate of the history of the Gītā, according to the Gītā itself and according to the version of the speaker, Lord Śrī Kṛṣṇa.
