I'm new to this series, and enjoying it a ton. However I know that the in game calendar is important and I'm feeling rushed. I've already had an NPC urge me to hurry up.
How do I know when I can freely explore, and when I need to scurry to the next plot point?
Please no spoilers. I'm just finishing BG1 chapter 2

The main storyline does not have a deadline.
Various sidequests do have deadlines. A number of possible party members will join you on the condition that you help them with a quest. You should do this reasonably quickly after they join you, or they'll leave to do it themselves:
Every other sidequest I know of with a time limit makes it explicit (eg. "you'll be dead in a week").
