About this tool
Sleep Chronotype Calculator helps you discover your natural sleep chronotype β Lion, Bear, Wolf, or Dolphin β using a science-based quiz. Your chronotype is your innate tendency to sleep and wake at particular times, determined by your circadian biology and genetics. This quiz assesses your sleep preferences, energy patterns throughout the day, and how easily you adjust to schedule changes to categorize you into one of four distinct chronotypes.
Complete the quiz by answering questions about your typical sleep-wake cycle, alertness at different times, and social preferences. The tool calculates your chronotype profile and provides a detailed description of your sleep characteristics, strengths, and optimal daily rhythm. Understanding your chronotype can help you align your work schedule, exercise routine, and social commitments with your natural biological rhythm.
Chronotypes are not fixed β they can shift subtly with age and seasons β but your core type tends to be stable throughout life. This tool is intended for self-awareness and scheduling optimization; it is not a medical diagnosis. If you experience persistent sleep problems, consult a sleep specialist or healthcare provider for personalized advice.
