Sunclock is a free browser-based daylight and photography planner. Check sunrise, sunset, twilight and golden/blue hour windows, explore the Sun's position, choose a preparation buffer, and export a calendar plan. Five US cities have reviewed detail pages; the planner also offers coordinate input. Times are astronomical estimates for a level horizon, not weather forecasts.

Could you build this?
Yes Sunrise, sunset, and twilight calculations are published algorithms (such as NOAA's solar equations), and the planner UI and calendar export are routine web work.
