By duration · Order from shortest to longest.

1. A single wingbeat of a hovering hummingbird 12.6 ms

   Up to 80 wingbeats per second lets hummingbirds hover, fly backwards, and even fly upside down — no other bird can do all three.

2. The world's longest scheduled flight, Singapore to New York 19 h

   The route covers about 15,300 km. The aircraft is configured with no economy class at all — partly so passengers survive the experience.

3. The Woodstock music festival of 1969 2.8 days

   Billed as '3 days of peace & music', it overran badly — Jimi Hendrix closed at 9 am on Monday to a field mostly littered with sleeping bags.

4. 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.

5. 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.

6. NASA's Perseverance rover travelling from Earth to Mars 203 days

   The 480-million-km cruise ended with the 'seven minutes of terror' landing — and the rover carried a small helicopter, Ingenuity, strapped to its belly.
