An 8-question, MEQ-style chronotype quiz. Find out if you're a morning lark, night owl, or intermediate — and get your ideal deep-work window and bedtime.
Answer 8 quick questions about your natural sleep, energy, and focus patterns. We'll score them MEQ-style and give you your chronotype — plus your ideal deep-work window, bedtime range, and tailored habit tips.

Your chronotype is the timing of your internal circadian clock — the biological reason some people are wide awake at 6 a.m. and others hit their stride at 9 p.m. It's largely set by your genes and your age, and it sits on a spectrum from strong morning types (larks) through intermediate types to strong evening types (owls). This quiz is modeled on the Morningness–Eveningness Questionnaire (Horne & Östberg, 1976), the self-report instrument sleep researchers have used for decades, collapsed into 8 representative questions and three buckets.
The practical payoff is timing. Your focus, working memory, and decision quality rise and fall with your circadian rhythm, so doing your hardest work during your natural peak — and protecting your sleep window — beats fighting your biology. Chronobiologists call the cost of fighting it social jet lag: the gap between when your body wants to sleep and when your schedule forces you to, which is linked to worse mood and metabolic markers without any productivity gain.
You can nudge your clock earlier or later by a couple of hours with consistent wake times and bright morning light, but you can't fully convert an owl into a lark. The bigger win is structuring your day around your type: schedule deep work in your peak window, keep a realistic and consistent bedtime, and stop treating an early-rising schedule as a moral virtue.
That's where a tracker helps. Once you know your deep-work window and ideal bedtime range, the hard part is showing up to them every day. Set them as daily habits in HabitBox — free, on-device, no account — and a one-tap check-in keeps your rhythm steady long enough for it to feel automatic.
Your chronotype is your body's natural preference for when to sleep and when you feel most alert — essentially the timing of your internal circadian clock. It exists on a spectrum from strong 'morning types' (larks) through 'intermediate' types to strong 'evening types' (owls). It's largely biological, partly genetic, and shifts gradually across your lifespan (most people are more owl-leaning as teenagers and drift earlier with age).
It's modeled on the Morningness–Eveningness Questionnaire (Horne & Östberg, 1976), the standard self-report tool used in sleep research. Each of the 8 questions awards 1 to 4 points, where higher answers lean 'morning.' We sum your answers (range 8–32) and place you in one of three buckets: Owl (8–16), Intermediate (17–23), or Lark (24–32). It's a quick estimate, not a clinical diagnosis.
Only within limits. You can nudge your clock earlier or later by a couple of hours using consistent wake times, bright morning light, and dimming screens at night — but you can't fully convert an owl into a lark. The bigger win is working with your chronotype: schedule demanding work in your natural peak window instead of fighting your biology and racking up 'social jet lag.'
Cognitive performance — focus, working memory, decision quality — rises and falls with your circadian rhythm. Doing your hardest task during your peak alertness window means it takes less effort and produces better output. The quiz gives you a recommended deep-work window for your chronotype so you can stop scheduling your most important work during your natural slump.
'Night person' is the casual version of an evening chronotype. The quiz makes it concrete: instead of a vague label, you get a recommended deep-work window, a realistic bedtime and wake range, and habit tips tailored to that type. That's the difference between knowing you're an owl and actually structuring your day around it.
