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. An episode of The Simpsons, without adverts 22 min

   The Simpsons is the longest-running scripted primetime series in US history — Bart has been ten years old for over three and a half decades.

3. An African elephant's pregnancy 1.8 years

   The longest gestation of any land mammal produces a 100 kg calf that can walk within hours — and is looked after by the whole herd.

4. The construction of the Great Pyramid of Giza 20 years

   Herodotus and modern estimates agree on roughly two decades — meaning workers placed a multi-tonne block about every five minutes of daylight.

5. The Berlin Wall standing, from construction to fall 28.2 years

   Since 2018, the Wall has been down longer than it ever stood — and more of it now sits in museums worldwide than in Berlin.

6. The Ottoman Empire 622.7 years

   Founded before the printing press, it ended after the airplane — the empire spanned 623 years and three continents at its height.
