Free tool / observation, not prediction
Follow the light. Keep the note.
Add the intervals when you observed direct sun reaching one specific spot on one date. Overlapping periods are counted once.
This is a manual observation log, not a sun-path model, forecast or plant-selection test. The sample times are fictional. Unobserved periods are unknown, not confirmed shade.
Your recorded direct sun
Enter observed intervals
Colored intervals = recorded direct sun. Pale intervals = no direct sun recorded; they are not automatically shade.

One spot. One day. One useful record.
Repeat observations on relevant dates rather than treating one day as a year-round result. The tool adds durations; it does not measure light intensity or choose crops. Compare your records with guidance for the actual plant and location.
