quick_answer: Quick answer: Rush hour is not one block of time. Morning and evening behave differently, direction matters more than the hour, and the evening peak is roughly twice as wide as most people plan for. US clock windows are typically ~7:00–9:00 a.m. and ~4:00–6:30 p.m., but your corridor and day decide the real answer — BoardSpy checks your saved route and tells you when to leave today.

faqs[5]{q,a}:
  What hours are rush hour?,Morning and evening rush hours have different shapes, which is why a single answer misleads. The morning peak is compressed because people aim at fixed start times. The evening peak is spread across several hours because people leave when their work finishes, so it builds earlier and drains more slowly than most drivers plan for.
  When does rush hour end?,Later than most people expect in the evening. The evening peak is typically about twice as wide as the morning one, and the tail clears gradually rather than stopping at a particular minute. The morning peak clears more sharply once the fixed start times have passed.
  Why is rush hour worse in one direction?,Employment concentrates at one end of most corridors, so traffic loads inbound in the morning and outbound in the evening. Travelling against that dominant flow is frequently 20 minutes faster on the same road at the same hour, which is why two people with identical commutes can have completely different experiences.
  Why does rush hour last longer on Friday?,Friday breaks the pattern in three ways: the evening peak starts earlier, it lasts longer, and it stacks weekend departure traffic on top of the normal commuter load. If you have one flexible day a week, Friday is where flexibility buys the most.
  Does leaving 15 minutes earlier actually help?,Usually more than 15 minutes' worth, because the delay curve is steepest at the shoulders of the peak rather than in the middle. A small shift at the right moment beats a large shift at the wrong one. If a 15-minute change saves you less than 15 minutes, you are already past the steep part of the curve.
