Game length and current turn number is mentioned in the bottom left of the status display in your phase (near the visibility number).
It can be seen and adjusted in game set-up through the view map screen as well in non-scenario games.
Scenario designers may or may not include the turn count in their text. Scenario text is only available in the scenario selection screen.

But game length is only a guide, as always.
- game length may extend if any objectives are contested
(roughly, some enemy forces not in retreat/rout are within ~300m)
The game has always been this way - it is there to stop a kamikaze rush of any outstanding objectives in the end turn with depleted units.

- the AI may throw the towel in early if its sufficiently beaten up, and the other side holds all objectives

PBEM games between humans tend to stick to the advertised turn count (but may still extend a move or 2).
