Ahh yes, the October Revolution celebrated in November...something about different calenders IIRC. Looking foward to this title now, although I have just brought WW1G - too many games, so little time.
This thread should go in the History Club forum, as I don't think many would celebrate this birthday. And you even didn't give a screenshot of the game related to.
Yes we used a different calendar. We were already in process of changing to western calendar but most of Russian Empire had not changed yet. We had on official documents after date saying "old calender" or "new calender" depending on the date used. Even into 20th.

It is national holiday in Russia, though officially it is named different many many people remember it for what it is.
