By duration · Order from shortest to longest.

  1. A single round of professional boxing 3 min

    Round length was standardized by the 1867 Queensberry Rules, which also introduced gloves — before that, bare-knuckle rounds ended only with a knockdown.

  2. A Eurostar train journey from London to Paris 2.3 h

    Only about 20 minutes of the trip is actually under the sea — the Channel Tunnel remains the longest undersea rail tunnel in the world.

  3. The Islamic holy month of Ramadan 29.5 days

    Because it follows the lunar calendar, Ramadan drifts about 11 days earlier each year — cycling through every season over 33 years.

  4. New Horizons' journey from Earth to Pluto 9.5 years

    It left Earth as the fastest spacecraft ever launched — and Pluto was demoted from planet status just seven months into the trip.

  5. Roman rule over Britain 366.9 years

    Rome governed Britain for 367 years — longer than the entire history of the United States — before abandoning it to defend Italy.

  6. The Republic of Venice 1.1K years

    The 1,100-year republic elected 120 doges using a bizarre multi-round lottery system specifically designed to prevent vote-rigging.
