Hofstadter’s Law: It always takes longer than you expect, even when you take into account Hofstadter’s Law.
This doesn’t always apply. It can, for example, leave you with an hour to kill at a train station, because you decided it would be really embarrassing to show up late for your ride to a CFAR workshop because of the planning fallacy.
