Ancient calendars found around the world are designed to end one point in time. They communicate an urgent warning to everyone alive today! Complex bronze and gold clocks with multiple dials are found in museums around the world. Why they have such advanced intricacy has stumped scientists for hundreds of years.This book reveals why the ancients built so many pyramids, observatories as well as those complex gold and bronze clocks with more than one dial. It surprised me greatly to discover that their various complex designs in one way or another converge on 21 December 2012. It amazes me that ancient cultures separated by thousands of miles of geography and thousands of years in chronology agree so precisely in the cyclical nature of time, history and prophecy, which is history written in advance. The most famous example is the Mayan-Aztec calendar, which ends its 25,626-year cycle on that momentous date. Some researchers have also found 21 December 2012 in what is called, the Bible Code. Using very different research methods, I discovered it in the Bible's book of Revelation and Daniel's prophecies. It is one of the most important dates in the plan of God for all humanity!
