The Phases of the Day's Light, in Order
Every day the light runs through the same sequence, set by how far the sun sits above or below the horizon. In the morning: astronomical, nautical, then civil dawn (sun climbing from 18° to 6° below the horizon), the morning blue hour (6–4° below), sunrise, and the morning golden hour (up to 6° above). The evening plays it back in reverse: golden hour, sunset, blue hour, dusk, and the three stages of twilight — civil, nautical, and astronomical — into night. Filmmakers bundle the whole low-sun stretch into one name: magic hour.
Every tool here works the same way: your browser's timezone reveals roughly where you are (no location permission, nothing sent to a server), standard solar equations do the rest, and an optional precise-location button refines the times to your exact spot.
