 ### 🌙 Night Dimming
-Between 22:00 and 06:00 local time, the backlight automatically dims to a softer brightness level - still perfectly readable, but easier on the eyes if the device sits in a bedroom or living room around the clock. This is separate from the inactivity screen timeout (**Menu → System → "Timeout"**), which turns the display fully off after a period of no touch input, regardless of time of day - handy if you just want the flight logbook running in the background without needing the screen. Tapping the screen wakes it back up to your configured brightness (or the soft night level above, if it's still within the night window).
+Between sunset and sunrise at your active location, the backlight automatically dims to a softer brightness level - still perfectly readable, but easier on the eyes if the device sits in a bedroom or living room around the clock. The dimming window follows the real sunrise/sunset time (calculated from your location and the current date), not a fixed clock window, so it automatically shifts earlier in winter and later in summer. Until the location or time of day is known (e.g. briefly after boot), it falls back to a fixed 10pm-6am window.

 Since this update, the same night window also softens the **radar screen itself** — aircraft markers and the rotating sweep line switch to darker green/yellow/red tones, so the whole display is easier on the eyes at night, not just the backlight. No separate toggle needed - it uses the same **Night dimming** setting.
