Define early, mid and endgame

Is there any accepted definition of when a game reaches midgame and endgame? Is it based on eras, turns, some event?

Early - ancient to classical
Mid - Medieval - Industrial
Late - Modern plus

I don't suggest it is 'accepted' but I think it works quite well.

Early finishes with you building National College.
Midgame finishes when you get an ideology.

This is IMO, which I admit is not backed up by years of play.

Early - Until Education / key tech for war (Mainly Machinery or Chevalry).
Middle - Until Plastics or Dynamite or Archeology.
End - Satellites or Flight/Electronics or Telecommunications.

Three cutpoints means four eras!

For me:
End of Early is the later of the following two (whichever happens first):

1. NC completed AND
2. If playing 3/4 city tradition tall then all your cities also founded; for Liberty I don't know; maybe if they have a noticeable gap in city founding at some point?

End of Middle game / beginning of Late game:
To me this is where the victory paths split:

If going for Culture victory: The moment you have tech for Hotels
If going for Science victory: The moment you have Plastics
If going for Domination victory: Naval variety: Techs for Battleships & Destroyers; Army variety: Probably the tech for Landships
If going for Diplomatic victory: The moment you start your deep beeline towards Globalization to the complete exclusion of every tech not on that path.

Beginning of End game:
Cultural: Moment you are influential over the first Civ (not counting crippled ones.)
Science: Moment you complete Hubble
Domination: When you are down to only 1 more capital to take on standard map size / 2 more capitals on Huge.
Diplomatic victory: The moment the World Council advances to Atomic Era (usually when someone hits Information era but can also be if a majority of civs actually reach Atomic Era)

For me: Early game=Ancient-classical era. Mid game=Medieval-Industrial era. Late game= Modern-Information era.

It's near the same as joncnunn for me.

Science :
Education/Plastics/Satellites

Diplomacy:
Education/PP/Plastics

Culture :
Education/Archaeology/Telecommunications

Domination :
Key tech/Artillery/Flight or Electronics

There are my cutpoints.

I think this is a good way to separate the cutoff points, everything else IMO is simply overcomplicated.

Find the oxymoron in my sentence...

Early : Composite Bowmen
Middle : Xbows
Late : Artillery
