Sunrise & Sunset is an Android application that calculates the time of day for dawn, sunrise, sunset, and dusk, based on the user's location and the time of year. The app is designed to help users plan their day around the sun's movements, and it is particularly useful for travelers and outdoor enthusiasts. One unique feature of this app is the graph view, which allows users to visualize how each event changes over the year. This feature can be very useful for educational purposes.

The app has a calendar view that shows the hour and minute when each event occurs, day by day. It also shows local times, using the user's current location, timezone, and day by default. Users can easily select another day by sliding the view left or right, and they can select another location using sliders for latitude and longitude. Additionally, users can create favorite locations and easily switch between these, making it easy to check sunrise and sunset times in advance.
