Best time of day
The best time of day for detail and review work.
Perceptual covers proofreading, checking, quality review and anything where small errors matter: proofreading a document, reviewing a contract, QA passes, checking figures.
Vigilance and error detection are strongest when alertness is high; they are the first to suffer after poor sleep and in the post-lunch dip.
By chronotype

strongest 6am to 11pmModel 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 detail and review work 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.
