How to use this result
A late sleep pattern often needs a paired change: a clearer morning start and a quieter evening finish. This planner keeps the shift small enough to repeat rather than forcing a dramatic reset.
The morning cue tells the body that the day has started. The evening cue removes the most obvious delay: bright ceiling light, close screen use or a routine that starts too late.
Use the same wake anchor for several days before judging it.
Best use
Run the tool, choose one change, repeat it for two or three nights, then compare the room notes. A repeated pattern is more useful than one perfect-looking number.
