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. Lent, from Ash Wednesday to Holy Saturday 46 days

   It's famously a 40-day fast, but the calendar span is 46 days — Sundays are feast days and traditionally don't count.

3. The Second World War 6 years

   From the invasion of Poland to Japan's surrender, it remains history's deadliest conflict — fighting officially ended on a battleship in Tokyo Bay.

4. One orbit of Pluto around the Sun 247.9 years

   Pluto hasn't completed a single orbit since its discovery in 1930 — it won't finish its first 'observed year' until 2178.

5. The Romanov dynasty's rule over Russia 304 years

   It began with a 16-year-old reluctantly accepting the throne in 1613 and ended 304 years later with Nicholas II's abdication in 1917.

6. The age of the Lascaux cave paintings 17K years

   Four teenagers and a dog named Robot found the caves in 1940 — visitor breath damaged the art so badly that today tourists see a replica.
