Features

The sun and shadows at a glanceTap the map to see the sun’s direction and height, and which way and how far shadows fall.
Shadows of nearby buildingsZoom in to see building shadows on the map, whether a spot is in sun or shade, and which hours it gets sunlight. Compare sunlight with and without buildings.
Your floor and windowCheck sunlight for a specific floor and window direction. The window direction is estimated from the building’s shape, and slopes and nearby hills are taken into account.
Any season in a tapChange the time and date with sliders, or jump to the equinoxes and solstices. Drag the sun on the map, or play the day from sunrise to sunset.
The sun as you see it in the skyToday’s sun path from where you stand, and the sun at the same time over a year (the figure-eight analemma).

Sun positions are astronomical estimates. Building shadows are approximate, based on open data from PLATEAU 3D city models (Japan) and OpenStreetMap (elsewhere), and need an internet connection; shadows from trees are not included. Building shadows can be turned off in Settings. The information shown is an estimate and its accuracy is not guaranteed. See the disclaimer on the support page for details.
