Chronotype quiz

Eight quick questions about when you sleep and when you feel sharp. Find out whether you're a lark, an owl or in between, and when to schedule your hardest work.

Question 1 of 8

If your day were entirely your own, what time would you get up?

The five types

TypeBest for deep workSecond peak
Early lark7 AM to 11 AM2 PM to 4 PM
Morning leaning8 AM to 12 PM3 PM to 5 PM
In between9 AM to 12 PM4 PM to 6 PM
Evening leaning11 AM to 2 PM5 PM to 8 PM
Night owl1 PM to 4 PM7 PM to 11 PM

Typical windows; your own best hours may sit an hour either side.

Why your chronotype matters for focus

Alertness rises and falls through the day on a curve set by your body clock. For most people it climbs through the morning, dips after lunch, and recovers in the late afternoon. Owls run the whole curve later. Putting your hardest work at your peak, and email and errands in the dip, gets more out of the same hours.

A mismatch between your body clock and your schedule has a name, social jet lag: the gap between when you sleep on work days and on days off. Our post on social jet lag explains it, and this one covers planning your day by chronotype.

Make the most of your type

  • Larks: protect the early hours, don't waste them on email, and keep late meetings rare.
  • In between: deep work mid-morning, admin after lunch, a second push late in the afternoon.
  • Owls: use mornings for easy, routine work; get daylight early to soften the start; save the evening for the hard problems. The deep work timer suits long evening blocks.

Questions

What is a chronotype?

Your body clock's natural timing: when you tend to get sleepy, wake up and feel most alert. Larks run early, owls run late, and most people sit somewhere in between. It's shaped partly by genes, and it shifts with age.

Is this quiz scientific?

It's modelled on the questions sleep researchers use, like Horne and Östberg's Morningness–Eveningness Questionnaire and the Munich ChronoType Questionnaire, but it's a short, informal version. Treat the result as a useful hint, not a measurement.

Can I change my chronotype?

Somewhat. Morning light, a regular wake-up time and dim evenings can pull your clock earlier by an hour or so, but they won't turn a strong night owl into a lark. Working with your type usually beats fighting it.

Does chronotype change with age?

Yes. Children tend to be early, teenagers and young adults shift markedly later (peaking around age 20), and people drift earlier again through adulthood and old age.
