Chronotypes: are you a morning lark or a night owl?

Your chronotype is not laziness or discipline. It is a rhythm your body keeps whether you like it or not, and you will have an easier time working with it than fighting it. To find yours, take the chronotype quiz. It takes about two minutes.

Everyone runs on an internal clock that roughly follows the day. It nudges you towards sleep at night and alertness in the morning. But the clock is set slightly differently from person to person. For some, the whole cycle runs early. For others, it runs late.

That is your chronotype. It shapes when you get hungry, when you concentrate best, when you feel sociable and when you hit the afternoon slump. It also changes over a lifetime. Teenagers famously drift later, and many people drift earlier as they get older.

We describe four chronotypes along a line from morning to evening.

• Morning Lark. You start while the street is still quiet. You may wake before the alarm, do your best work before lunch, and be ready for bed while friends are ordering another round. More on the Morning Lark.
• Early Riser. Mornings suit you, once the kettle has boiled. You are productive early, steady through the day and happy with a sensible bedtime, though a late night now and then will not floor you. More on the Early Riser.
• Late Riser. Your best hours arrive after lunch. You get through the morning, but your real focus and energy show up in the afternoon and early evening. More on the Late Riser.
• Night Owl. The day begins properly once everyone else has gone home. You think clearest late, find early starts genuinely hard and often have your best ideas when the house is quiet. More on the Night Owl.

Our chronotype quiz is our own questionnaire: twelve questions about when you naturally wake, when you feel at your best and how you would plan a free day. Each answer carries points, and your total places you on the line from evening to morning. Higher totals mean more of a morning person.

Answer for a free week rather than a working one. The question is when you would sleep and wake if nobody set an alarm for you.

Some everyday clues:

• On holiday, with nothing to get up for, when do you naturally wake? Larks are up with the light. Owls sleep in and stay up.
• On a free evening, do you get a second wind around ten, or are you yawning by nine?
• When do you do your best thinking? Larks often write the important email first thing. Owls do it after dinner.
• How do you feel about breakfast? Larks are often hungry early. Owls can easily skip it.
• How do weekends go? If you sleep much later on Saturday than on a weekday, your natural rhythm is probably later than your alarm.

You cannot always choose your hours, but you can usually choose what you do in them.

• Put your hardest thinking in your peak. Larks: tackle the big task before mid-morning. Owls: protect a late afternoon or evening block for it.
• Save routine work for your dip. Email, admin and tidying are fine in the slump. Planning and writing are not.
• Get daylight early. Natural light in the morning helps set your clock. A short walk before work is one of the simplest things any chronotype can do.
• Keep the evening calm. Dim lights and a screen-free half hour before bed make sleep easier, especially for owls trying to shift earlier.
• Be consistent. A similar wake time every day, weekends included, steadies your rhythm far more than an occasional early night.
• Shift slowly. If you need to move your schedule, do it in small steps over a couple of weeks rather than all at once.

Chronotypes explain a lot of everyday friction. The lark who wants a breakfast meeting and the owl who does their best work at nine at night are not being difficult. They are both at their peak, just at different times.

At work, it helps to say it out loud. "I'm sharpest first thing, can we do the planning meeting at nine?" or "I'll send this over this evening when I can focus" is far more useful than quietly struggling.

At home, mixed couples can make it work with a bit of planning. Share the evening meal, then let the lark go to bed and the owl have the quiet hours. Agree on a shared morning routine that suits the lark without dragging the owl out of bed an hour early.

The aim is not to turn an owl into a lark. It is to give your natural rhythm as much room as your life allows, and to keep a steady routine for the rest.

If you know your chronotype, you can choose a better time for the gym, plan your study sessions, pick shifts that suit you and stop feeling guilty about being who you are at seven in the morning.
