Nine quick questions about your natural sleep, energy, and alertness place you on the morning–evening spectrum. You'll get your chronotype, a suggested work window to test, and concrete guidance on when to schedule your hardest work.
Answer for your natural preference — how you'd live if your schedule were entirely your own, not what your job or alarm currently forces. There are no right answers, and completed report snapshots are saved locally in My AurorIQ.

This questionnaire summarizes your reported timing preferences. It does not measure your body clock or peak performance. Compare similar tasks at two feasible times, record effort and errors, and preserve sleep and daily commitments.
About this instrument
This questionnaire summarizes your reported timing preferences. It does not measure your body clock or peak performance. Compare similar tasks at two feasible times, record effort and errors, and preserve sleep and daily commitments.
Original questions inspired by the morningness–eveningness literature, each weighted toward morning or evening. Your total places you in one of five bands from Definite Evening to Definite Morning.
Your chronotype, your position on the spectrum, a suggested work window to test, and specific guidance on when to schedule demanding work versus routine tasks.
Self-report reflects how you see your rhythm, not always how your body behaves. It's a snapshot that shifts with stress and age, and it's never a sleep-disorder screen. Track your real energy to confirm.
Questions
Chronotype describes a tendency toward earlier or later timing for sleep and activity. Biology, age, light exposure, habits and social schedules can all influence the pattern; this questionnaire estimates self-reported preference rather than directly measuring circadian phase.

No. This is a self-reflection tool that estimates your morning–evening preference, not a clinical assessment. It can't diagnose insomnia, sleep apnea, or any disorder. If you regularly struggle to sleep or feel exhausted no matter your schedule, that's worth raising with a doctor.
No. The test runs entirely in your browser. The task engine does not upload individual answers. Hosting, analytics, advertising and any sharing you choose are separate; see the privacy notice. Refreshing the page clears everything.
Scoring & evidence
The chronotype tool uses nine original preference questions inspired by morningness–eveningness research without reproducing a proprietary clinical questionnaire. Each answer contributes a morningness value. The total is normalized between the minimum and maximum possible scores to a 0–100 morningness index and then mapped into descriptive bands with general peak-time guidance.

The result cannot diagnose insomnia, delayed sleep-wake phase disorder, sleep apnea, or another sleep condition. It is a planning aid for thinking about when you tend to feel alert, not a medical assessment.
Interpretation standard: observations describe this task; internal indices are model or response summaries, not population rankings. Use the report for education and reflection. See the methodology for limitations.

Morning–evening preference has a research history, including the questionnaire described by Horne and Östberg. AurorIQ’s nine-question implementation is not that validated instrument and does not measure circadian phase or an exact peak-performance time.
