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?
