I struggled with this one for a while too, but I noticed on one of the loading screens it had a blurb about this. As far as I'm aware Stronghold turns are related to quest objectives. Turns occur whenever you complete quests in the game - main story line or side quests, as far as I've noticed (not sure about tasks). This is why many days can pass without a turn taking place and suddenly you can have a veritable plethora of turns occur over the course of a single day.
