What's your chronotype?

A quick five-question self-assessment based on the Munich Chronotype Questionnaire structure. Your result personalizes the light windows on the planner.

1. If you were completely free to plan your day, what time would you get up?
2. How alert do you feel during the first half-hour after waking?
3. At what time in the evening do you feel tired and in need of sleep?
4. At what time of day do you usually feel your best?
5. One hears about 'morning' and 'evening' types. Which do you consider yourself?

The three chronotypes

Everyone has a natural biological clock. Discovering yours is the first step to better sleep.

Morning Lark

You naturally wake before sunrise and feel most alert in the early morning. Your optimal light window starts before dawn. You may struggle with evening social events.

Wakes ~06:00 Peak alertness 08–12 Sleeps ~22:00

Dove (Intermediate)

You fall in the middle of the spectrum. A standard sunrise-aligned schedule works well. Your alertness is fairly consistent across the day with a natural dip after lunch.

Wakes ~07:30 Peak alertness 10–14 Sleeps ~23:00

Night Owl

You naturally run later. Your alertness peaks in the evening and you may struggle with early starts. Your light plan shifts later to match your biology.

Wakes ~09:30 Peak alertness 18–22 Sleeps ~01:00
