SunTrajectory.net enables you to predict the sun path and its shadow.

Use your camera and view it live!
Find sunrise and sunset times, not only on the horizon, but also depending on a building or a mountain.

SunTrajectory.net allows you to display the future trajectories of the sun in augmented reality:
* Look through your phone and see the path of the sun.
* Plan the sunrise and sunset times, not only on the horizon, but also on a building or a relief.
* Travel in time and see what course the sun will follow in the months to come.

MoonTrajectory.net is included:
* Find out if the moon will be full or what phase it will be in.

Architecture:
* Visualize the sunlight in and out of a house you wish to buy for every month of the year.
* Predict the consequences of a shadow.
* Think about the orientation of a terrace, imagine creating a new window.

Photography:
* Plan your pictures according to the light effect you wish to create.
* Plan when a subject (like a statue for instance) will be lit from the angle you have chosen.
* Plan when that same subject will be aligned with the moon.
* Use the calendar of the moon phases.
* Plan when the sun will light a scene (and not be hidden by a mountain or a building).
* Imagine the outline of shadows on the scene at a later date.
