The sun's exact position comes from the NOAA solar algorithm using each stadium's real coordinates, date, session time and timezone — so the sunny vs. shady side and the timing are reliable. The seating bowl is split into individual sections (each sideline, baseline and corner, across lower/mid/upper tiers); every section is ray-traced against the tiered bowl, oriented to the court's true bearing (championship courts run roughly north–south, so neither baseline player faces the sun). Court orientation is pulled live from OpenStreetMap geometry where available ("map-derived"); otherwise a built-in estimate is used ("estimate"). The bowl geometry is a calibrated physics approximation, not exact per-stadium CAD — treat the shaded side, sweep and timing as the reliable signal, and exact section cutoffs as approximate. Retractable roofs (Arthur Ashe, Louis Armstrong) follow the toggle; the Miami Open stadium court sits inside Hard Rock Stadium, whose canopy shades much of the seating. Day sessions typically start around 11am–noon, night sessions around 7pm. Exact tournament dates shift slightly year to year — check the official schedule when buying.
