Does anyone how and where do you edit the game calendar?

welcome to the forums. Thanks to strategyonly I do know this now :)

If your wanting to only do it for a single scenario, you should get it into CivwarlordsWBSAVE format and then open with notepad (or whatever) and you can change calendar to the following settings.

CALENDAR_DEFAULT
CALENDAR_BI_YEARLY
CALENDAR_YEARS
CALENDAR_TURNS
CALENDAR_SEASONS
CALENDAR_MONTHS
CALENDAR_WEEKS

you can also do this with the xml I believe in the civ4globaldefines.xml

Can probably make a custom calendar also, but that would require much much more work.
