Original Summary

I&#x27;ve been a photographer for decades, and for a long time I&#x27;ve wanted to make an app that will tell me when the sun&#x27;s light will directly hit the&#x2F;a surface of a building.<p>This weekend I found the time to build and launch a thing that does that. Features include:<p><pre><code> - Enter an address, get back a map with calendar details and some dataviz on when the sun is going to hit each wall - Save buildings, walls, and dates in a Planner, with a Calendar feed - Analyze the sun between two points along a street (currently limited to 5km along a single street) - Share links to what you&#x27;ve found </code></pre> Sources used include: OpenStreetMap, Nominatim, Photon and the US Census Bureau geocoder. Sun positions come from the NOAA solar position algorithm, computed in-browser. Cloud forecasts from Open-Meteo.<p>I hope you find it useful, and welcome feedback!
