Morningness–eveningness questionnaire

Sometimes people are more awake and active in the morning, and sometimes they are more awake and active at night. This is called being a "morning person" or an "evening person." The morningness-eveningness questionnaire is a set of questions that helps you figure out if you are more of a morning person or an evening person. The questions ask things like what time you wake up in the morning, what time you go to bed at night, and when you feel most awake during the day. By answering these questions, the test can tell you if you are more suited to waking up early and being active in the morning, or staying up late and being active at night. It just helps you understand yourself better and plan your daily routine accordingly.
