Chronotype Assessor
Identify your biological circadian preference (Morningness vs Eveningness).
1. If you had no commitments and could choose entirely freely, what time would you get up?
2. During the first half-hour after waking up, how tired do you feel?
3. At what time of day do you feel your absolute peak energy?
Estimated Chronotype:
Do not fight your biology if you don't have to. Align your most demanding cognitive work with your peak hours.
Methodology & Assumptions
Genetic Determination
Chronotype is largely dictated by genetics (specifically variations in the PER1/PER2/PER3 genes). Society historically punishes "Owls" by forcing them into early industrial schedules, resulting in chronic social jetlag. This tool uses a compressed variation of the Horne-Östberg Morningness-Eveningness Questionnaire.
