Turn length?

I expected each 'turn' to be one season, Winter,Spring, Summer etc...but they seem shorter. How long are they and is there any way of seeing the date and not just the year you are on?

Each turn without modding is 2 years with a season change.

You can also change the display to show year rather than turns.
To do so, edit your descr_strat.txt file by putting a semi-colon (;) before show_date_as_turns
To change the amount of years in each turn, check the first link in my signature.

Each turn is 2 years, but the season changes between summer and winter each turn. For example, 1080 is summer, next turn 1082 is winter, 1084 is summer and so on.

I did the same thing FH recommended to display year instead of turn. Except I didn't put a ';', I changed it to 0 or 1 or true or false (i don't remember exactly) the point is to change it to the opposite of whatever it is by default.

Erm, that variable is:
show_date_as_turns

No 0 or 1 involved. Just put a ; (comment) in front of it to make the game skip that line, thus dispaying as years.

As always, FH is right, i do in fact have a ; in front of that text.
