Best time of day
The best time of day for learning and abstract thinking.
Conceptual covers reading to understand, studying and connecting ideas: reading a dense paper, learning a new tool, synthesising research, writing an argument.
Encoding new material benefits from alertness, and consolidation benefits from sleep, so learning before a good night tends to stick.

Model output for a neutral energy level and eight hours of sleep, from the baseline and chronotype tables on Sources. Timing effects are real but not universal; a person's own check-ins move these curves.
How to use this
- Find your chronotype above. If you wake easily before 7 and fade by 9pm, read the morning row; if the reverse, the evening row.
- Put your hardest learning and abstract thinking in the strongest range and protect it: no meetings, no inbox.
- Put routine work in the weak hours. It does not need your peak.
- Keep the same slot for a week, then judge by output, not by how it felt on day one.
Or let the schedule do it.
My Calendy maps your own curve from four answers, breaks a project into tasks, and places each one at the hour your brain is best at that kind of work, around your calendar. When a block slips, it re-plans. 7 days free, no card.
