An eon is the largest division of geologic time, lasting billions of years. An era is a subdivision of an eon, typically lasting hundreds of millions of years. A period is a smaller division of geologic time, lasting millions of years, and an epoch is an even smaller division of time, typically lasting tens of millions of years.
Eon, Era, and Epoch: APEX :D
Eon, era, period, epoch.
Eon, era, period, epoch.
The order from largest to smallest is eon, era, period, and epoch. Eons are the longest divisions of time, followed by eras which encompass multiple eons, then periods which are subdivisions of eras, and finally epochs which are subdivisions of periods.
The geologic time intervals from longest to shortest are eon, era, period, epoch, and age. This hierarchical sequence represents the largest divisions (eons) to the smallest subdivisions (ages) of Earth's history.

We currently live in the Holocene Epoch of the Quaternary Period of the Cenozoic Era of the Phanerozoic Eon.
Eon, era, period, epoch.
A long period of time is commonly referred to as an era or epoch.
It is between 488 and 542 million years old. It is in the middle epoch of the Cambrian period. It is in the paleozoic era and the phanerozoic eon.
The smallest unit of geologic time is an age, followed by epoch, period, era, eon, and super eon.
The order from largest to smallest is eon, era, period, and epoch. Eons are the longest divisions of time, followed by eras which encompass multiple eons, then periods which are subdivisions of eras, and finally epochs which are subdivisions of periods.
The smallest unit of time on the geologic time scale is an epoch, which typically lasts millions of years. It is used to divide periods into smaller segments based on significant changes in Earth's history.
The geologic time intervals from longest to shortest are eon, era, period, epoch, and age. This hierarchical sequence represents the largest divisions (eons) to the smallest subdivisions (ages) of Earth's history.
In geological time a period is smaller than an era but larger than a Epoch.The International Commission of Stratigraphic have divided the time as such from largest to smallest.Super-Eon - (SuperEonothem) (Not recognised by the ICS but unofficially recognised e.g. Precambrian time)Eon - (Eonothem)Era - (Erathem)Period - (System)Subperiod - (SubSystem)Epoch - (Series)Age - (Stage)Chron - (Chronozone) (Not recognised by the ICS but is unofficially recognised usually based on reversal of earths magnetic field)
Eon - Phanerozoic (most distant) Era - Cenozoic Period - Quaternary Epoch - Holocene (most recent)
