The SunCalc module allows to calculate sun position, sunlight phases (times for sunrise, sunset, dusk, etc.), moon position and lunar phase for the given location and time.
SunCalc was ported to Haxe by Robin ypid Schneider to allow using it in a planed rewrite of the opening hours library.
It is based on the JavaScript implementation created by Vladimir Agafonkin (@mourner) as a part of the SunCalc.net project.
Most calculations are based on the formulas given in the excellent Astronomy Answers articles about position of the sun and the planets. You can read about different twilight phases calculated by SunCalc in the Twilight article on Wikipedia.
Refer to the API documentation for details.
Install the library for your favorite language by executing one of the following commands:
haxelib install suncalc # Haxe
npm install suncalc # JavaScript/Node.JS
composer require ypid/suncalc # PHP- C++

The following limitations seems to be related which should mean that when they are fixed for one target, the tests for the other targets should also pass. If you need SunCalc.getMoonTimes for one of those targets, feel free to debug it further.
- Python:
SunCalc.getMoonTimes(risedate can not be calculated.). - C++:
SunCalc.getMoonTimes(segmentation fault). - Java:
SunCalc.getMoonTimes(java.lang.NullPointerException). - Neko:
SunCalc.getMoonTimes
