Chronotype Quiz: Discover Your Sleep Type and Optimal Daily Schedule
Discover your chronotype and get your ideal sleep schedule and peak hours
About Chronotype & Sleep Time Quiz
Your chronotype — whether you're a morning lark, a night owl, or an intermediate — is approximately 50% determined by genetics, specifically variants in circadian clock genes including CLOCK, PER3, and CRY1. Research by Professor Till Roenneberg at the University of Munich, whose Munich Chronotype Questionnaire (MCTQ) has been validated on over 220,000 participants, shows that working against your chronotype — which modern work schedules frequently force — creates "social jetlag" that measurably impairs cognitive performance, metabolic health, and wellbeing. This free Chronotype Quiz uses the MCTQ methodology to identify your chronotype and generate your personalised optimal daily schedule.

4Check for Social Jetlag
The quiz calculates your social jetlag — the discrepancy between your biological sleep phase and your actual schedule. Each hour of social jetlag is associated with measurable health and performance impacts.

Frequently Asked Questions
What is a chronotype?
A chronotype is your biological preference for sleeping and waking at certain times, driven by your individual circadian rhythm. Chronotypes follow a normal distribution: approximately 25% are morning types (larks), 50% are intermediate, and 25% are evening types (night owls). Your chronotype is approximately 50% genetic, shifts with age, and cannot be overridden by willpower alone.
How do I know if I am a morning person or night owl?
The clearest indicator is your natural (unconstrained) sleep timing on free days when no alarm is set. Morning types naturally sleep around 10pm-6am; intermediate types around 11pm-7am; evening types around midnight-8am or later. If you feel genuinely alert within 30 minutes of waking naturally, you are likely a morning type.
Can I change my chronotype?
Chronotype can shift modestly with consistent morning bright light exposure (10,000 lux for 20 minutes immediately upon waking) and strict sleep timing. Chronotype also naturally shifts earlier with age — teenagers typically have the latest chronotypes, which shift progressively earlier from the mid-20s onward. You cannot override your genetic baseline through willpower or motivation.
What is social jetlag?
Social jetlag is the discrepancy between your biological sleep phase and your socially imposed schedule (work, school). Professor Roenneberg's research found 70% of the population has at least 1 hour of social jetlag. Each hour of social jetlag is associated with a 33% increase in obesity risk, measurable cognitive impairment on weekday mornings, and higher rates of metabolic syndrome.
