Sunlight Planner

Plan the light before you go. See sunrise, sunset, daylight and solar noon for a chosen date and location. Read geometric golden and blue light windows, then save the plan and your notes. Choose Los Angeles, New York, London or Sydney with date-aware daylight saving time, or enter coordinates and a UTC offset. Saved plans stay on your device. New saves can restore their location, date and notes; older text-only saves remain available as original summaries. Share a plan with the native share sheet. Calculated with NOAA/Meeus solar position. Golden light uses −4° to +6°, blue light −6° to −4°, and sunrise/sunset −0.833°. Estimates assume an unobstructed horizon; weather, terrain, buildings and elevation can change visible conditions. No weather forecast, automatic location lookup, account, ads, subscription or in-app purchase.
