SAGA GIS also has a tool for it since 2015:

  Climate -> Tools -> Sunrise and Sunset

It is raster data based: "This tool calculates the time of sunrise and
sunset and the resulting day length for each cell of the target grid.
The target grid needs to provide information about its coordinate system."
