Clarity before you drive.
Exact sun position on your route, minute by minute. See where a low sun will be in your eyes, for how long, and when to leave instead.
How Glare works
Type where you are leaving from, where you are going, and when. Glare fetches the driving route, splits it into short segments with their own heading and arrival time, and computes the sun's altitude and bearing at each one with NOAA solar geometry, verified to a tenth of a degree against an astronomical ephemeris. A segment counts as sun in your eyes when the sun is low enough to sit under the visor for your kind of car and within 35° of the road's heading.
The result is the minutes of glare, the exact windows on which roads, a departure slider that moves the sun with it, the coming-weeks strip that names the day the commute goes clear, and a driver's-eye 3D drive with the real sun in the windshield. Side windows and mirrors are reported on their own line. The cloud forecast changes the wording, never the geometry.
Not modelled, and said so: hills, trees and overpasses that block the sun, other vehicles, live traffic, windshield tint. Read the accuracy guide, this week's numbers for fifty cities, or why the sun finds the same commute every September.
