Miracle Calculator (Littlewood's Law)

Your details

Length of the time period you want to analyze.
Littlewood assumed 8 active waking hours. You can adjust this to match your own routine.
h
How many distinct events your brain consciously registers each second. Littlewood used 1 per second as a conservative baseline.
/s
Littlewood defined a miracle as any event with a one-in-a-million chance. Lower this to explore less rare events, or raise it to model truly exceptional occurrences.

In 1 years, probability predicts about 10.5 miracles.

  • You consciously register about 28,800 events each day, and roughly 10,519,200 over 1 years.
  • At 1-in-1,000,000 probability, Littlewood's estimate holds: expect roughly one miracle every 35 days.
  • Over a full 80-year lifetime you would experience roughly 842 such events.
  • Littlewood's point is not that miracles are supernatural, but that improbable events are statistically guaranteed to happen regularly to everyone.

Next stepTry raising the "miracle probability" input to 10,000,000 (one in ten million) to model truly rare once-in-a-lifetime events.
