Lark, owl or in between? A quick body-clock check
You will be able to: Place yourself on the morning-to-evening range, and know why it matters for your anchor time.
People differ in when their body clock wants them asleep and awake. Scientists call this your chronotype. Most people sit somewhere in the middle, with smaller groups leaning clearly towards early ("larks") or late ("owls").
Your type is not fixed for life. A study of more than 50,000 people in the US found that, on average, people get later through the teenage years, reach their latest at about 19, and then drift earlier again with age.
Answer for free days, when you do not have to fit anyone else's timetable.
