The Founding of Astronism, also colloquially named the eight year revelation (not to be confused with the event of the Eight Year Revelation), or simply as the Founding era, is the first period in the chronology of Astronism and is an historical period of time which remains greatly intertwined and dependent upon the narrative and life events of Cometan. Astronism was founded in 2013 by Cometan.

The Founding of Astronism is a time period which encompasses the formative years of the organised philosophy, particularly between the years of 2013 and 2020. The Founding of Astronism is therefore characterised by the philosophy's initial conceptual developments, namely in branches of theology and philosophy. The Founding of Astronism is followed by the period of The Establishment of Astronism.
