Test sun exposure calculation with adjustable positions
This is a rough estimation for planning purposes. It assumes perfect weather, flat terrain, and constant driving speed. Real-world conditions like buildings, trees, and weather will affect actual sun exposure.
The tool uses UTC time for all calculations. Convert your local departure time to UTC before entering it.
Yes, if the tool shows high sun exposure on one side, you can choose to sit on the opposite side for a more comfortable journey.
Route Planner analyzes real driving routes. Test Mode lets you manually adjust positions to understand the calculations.
