SunCalc - Sunrise and Sunset Calculation

SunCalc is a simple Java project that calculates the sunrise and sunset times based on geographic location and date. The project uses astronomical formulas to accurately calculate the sunrise and sunset times.

Requirements

• Java Development Kit (JDK) 8 or higher

Project Structure

The project is organized into the following classes:

1. SunCalc: Main class that performs the sunrise and sunset calculations.
2. Location: Class representing the geographic location with latitude, longitude, and time zone (UTC).
3. TimeUtils: Utility class containing time conversion methods.
4. SunriseAndSunset: Class containing the main method to run the application with examples.

Usage

To use the project, follow these steps:

1. Compile and run the SunriseAndSunset class in your favorite Java IDE.
2. Configure the location for which you want to calculate the sunrise and sunset times in the SunriseAndSunset class. Set the latitude, longitude, and UTC values in the Location object.
3. Run the application, and the sunrise and sunset times will be printed to the console.

Example

Here's an example of how to set up a Location object and use the SunCalc class:

Location location = new Location();
location.setLatitude(-33.2394434);
location.setLongitude(-60.318236);
location.setUtc(-3);

LocalDate day = LocalDate.now();
SunCalc sunCalculator = new SunCalc(day);

LocalTime sunrise = sunCalculator.calculateSunriseHour(location);
LocalTime sunset = sunCalculator.calculateSunsetHour(location);

System.out.println("Sunrise: " + sunrise);
System.out.println("Sunset: " + sunset);
