Hello, the Bible itself does tell us that no one knows when the End of the world will come, only the father knows that information. This would rule out different types of prediction, but people have tried anyway. The most noted is the Mayan and their calendar that pointed toward 2012 as the year of the End. By awaiting the exact time, it could be said that the Mayans calendar has been a little off and just to reverse the year of 2012 to 2021. The end of the world was clearly marked by: COVID-19, Extreme Weather, Economic collapse.
Matthew 24:36
Living Bible
36 But no one knows the date and hour when the end will be—not even the angels. No, nor even God’s Son. Only the Father knows.
