In general speech, an eon can refer to a very long period of time.
In science, an eon is the largest division in the geologic time scale. An eon is subdivided into two or more eras and lasts around a billion years or so. In Earth's history there are four eons in total: Hadean, Archean, Proterozoic, and Phanerozoic. We are currently in the Phanerozoic Eon.

Most scientists agree that there are 3 eras for every eon.

The oldest eon of geologic time is the Archaean Eon of the Precambrian period. The oldest rocks and fossils date from this time, about 3.8 to 2.5 billion years ago. (Prior to that, the Hadean Eon began with the formation of the Earth. No geologic record exists from the Hadean, during which the Earth cooled from its molten state.)
The end of the Precambrian Eon is marked by the beginning of the Phanerozoic Eon, approximately 541 million years ago. This transition is characterized by a significant increase in the diversity of multicellular life forms and the appearance of abundant fossils in the geological record.
The eon after the Hadean Eon is the Archean Eon. During this eon, significant geological and biological events took place, leading to the development of early life forms on Earth.
