Chronotype test: are you a morning or evening person?
Six questions to gauge your rhythm: morning Lion, intermediate Bear, evening Wolf or light-sleeping Dolphin. Instant results, with what you can adjust.
Short answer
Your chronotype is your natural preference for mornings or evenings. It depends partly on your genes, changes with age and is measured scientifically using questionnaires such as the MEQ. The four animals in this test are a general guide, not a diagnosis.

Answer 6 questions to discover your chronotype. Choose the answer that best matches you.
1. Without an alarm, what time do you naturally wake up?
2. What time of day are you most productive and focused?
3. What time do you prefer to go to bed (when you can choose)?
4. Are you hungry when you wake up?
5. How do you react to caffeine?
6. Does your schedule change on weekends or vacations?

What it means
What you can adjust
A typical day
💡 The four animal profiles come from a popular model. They offer a reference point, but only questionnaires such as the MEQ or MCTQ have been scientifically validated.
💡 Chronotype changes with age: it shifts towards evenings during adolescence, then gradually back towards mornings in adulthood.
💡 For a more precise analysis, combine this test with our Sleep Window and theSleep Analyzer.
What the tool measures
What science really says about chronotype
Your internal clock does not run on exactly the same schedule as your neighbour's. Some people wake naturally at 6 am; others are not really up to speed until late morning. It is not about willpower: a genetic study of nearly 700,000 people identified more than 350 regions of the genome associated with chronotype.
Chronotype also shifts with age. It moves towards the evening during adolescence, reaches its latest point at around age 20, then gradually shifts back towards the morning. Light, especially morning light, remains the main way to shift it.
The four profiles—Lion, Bear, Wolf and Dolphin—come from a model popularised in a book for the general public. They are easy to remember but have not been validated like the MEQ or the Munich Chronotype Questionnaire (MCTQ). The Dolphin actually describes light sleep rather than a preferred time.
Interpreting the result
Interpret without overpromising
The test selects the profile matching the largest number of your answers:
- Lion: morning preference.
- Bear: intermediate profile, the most common.
- Wolf: evening preference.
- Dolphin: light or irregular sleep, rather than a preferred time.
A score split between two profiles is common: you fall somewhere between them. What matters most is the gap between your natural rhythm and your imposed schedule. A large gap between weekdays and weekends, called social jet lag, is associated with greater fatigue.
Calculation and assumptions
Methodology
- Six questions cover your natural wake-up time, when you feel at your best, your preferred bedtime, hunger on waking, your response to caffeine and your weekend rhythm.
- Each answer corresponds to a profile. The profile with the most answers is selected. In a tie, the first in the order Lion, Bear, Wolf, Dolphin wins.
This is a guidance questionnaire designed by the site, not a validated tool. For a reference measurement, the Horne and Östberg MEQ has 19 questions.

Scope of validity
Limitations to know
- This test is not scientifically validated. It offers guidance, not a measurement.
- Your answers also reflect your current constraints: shift work, young children or a fixed wake-up time can mask your natural rhythm.
- Unrefreshing sleep, frequent waking or daytime sleepiness are not chronotype issues. If they last more than three months, talk to your doctor.
Frequently asked questions
Before using the result
What is a chronotype?
It is your natural preference for being active in the morning or evening. It depends partly on genetics, age and light exposure.
What is the most common chronotype?
The intermediate profile, the Bear in this test. Strongly morning or late-evening profiles are in the minority.
Can you change your chronotype?
Partly. Morning light shifts your clock earlier; evening light shifts it later. Age also shifts it: later during adolescence, then earlier afterwards.
Are the Lion, Bear, Wolf and Dolphin profiles scientific?
They come from a model for the general public. They are practical, but only questionnaires such as the MEQ or MCTQ have been validated in studies.
Is being an evening person bad for your health?
The main problem is the mismatch with imposed early schedules, which creates sleep debt during the week. Keeping regular hours and getting morning light limits this mismatch.
