Timeline

This is a list of historical events placed in the Selenial Calendar.

The Selenial Calendar pegs the latest Canterlot eclipse as day 1 of the year 1001. The reasoning for this is the mythological departure of Princess Luna a thousand years before, although her departure happened in the early 7th century of the common era.

Ancient times
