The eon of endurance lasts one intermediate eon in its initial phase and one intermediate eon in its final phase, plus the eighteen intermediate epochs between them.

The initial phase is the period of one intermediate eon where the lifespan decreases from an incalculable period to a lifespan of ten years.
