By duration · Order from shortest to longest.

1. A football (soccer) match, regulation time 90 min

   The ball is typically in play for barely 55 of those minutes — which is why competitions now add increasingly enormous stoppage time.

2. Yuri Gagarin's entire Vostok 1 spaceflight 108 min

   The first human spaceflight was a single orbit — and Gagarin ejected and parachuted down separately from his capsule, landing in a potato field.

3. A chicken egg's incubation, laying to hatching 21 days

   Chicks start cheeping to their mother through the shell a day or two before hatching — and she clucks back to encourage them out.

4. A horse's pregnancy 340 days

   Foals can stand within an hour of birth and gallop within a day — a survival feature for a prey animal born on open grassland.

5. The main construction of Notre-Dame de Paris 97 years

   The medieval build ran from 1163 to 1260 — yet after the 2019 fire, the cathedral was restored and reopened in just five years.

6. How long the Hagia Sophia has been standing 1.5K years

   Built in just five years under Justinian, it has since served as cathedral, mosque, museum, and mosque again across nearly 1,500 years.
