## Direct Answer

Set a location and the outward direction of a window or balcony to find potential sun exposure periods. Coloured trajectories compare up to three additional dates on the sun-path diagram.

## Key Facts
- Potential exposure requires the sun above the horizon and within 90 degrees of the outward-facing direction.
- Assumes a vertical face with no obstructions; buildings, trees, hills, overhangs and window recesses are not modelled.
- Times are approximate to one minute, in the selected location’s time zone. They do not predict indoor brightness or actual direct-sun duration.

## Common Uses
- Explore morning or afternoon exposure for a window or balcony.
- Compare seasonal sun trajectories before checking surrounding shadows in the app.
