Abstract:

The system of the Christian Era consists of "Christian Era"and "Before the Christian Era".It went through more than 1000 years from its initial establishment to final accomplishment and accompanied a course of the rise and fall of Christian History. As a unique way of numbering the years that could best embody characteristics of Christian History, the Christian Era was put forward with an enhancement of Christians' "consciousness", and was set up in the wake of maturity of Christian History. The "Before the Christian Era" was put forth and popularized as an auxiliary means when Christian History's chronological system had bogged down more deeply in crises. It hastened the decline of Christian History though it made the way of numbering historical years convenient and promoted studies of ancient history.

Key words: Christian History, Christian Era, Before the Christian Era, Annus Mundi
