The Sunrise software

We have our own proprietary software which calculates the time and azimuth of sunrise and sunset for anywhere in the world.

The single-page printout shows the following:

  • Start of Civil Twilight
  • Sunrise Time
  • Sunrise Azimuth
  • Daylight hours
  • Sunset Time
  • Sunset Azimuth
  • End of Civil Twilight
  • Moon Phase

The printout also shows a Solar Location Diagram, which can be used to work out where the sun will be in the sky at any given time during the day:

These figures, and the azimuths supplied, already take into account the Magnetic Declination, i.e. the difference between Magnetic North and True North.

Location Works provides a one-week Sunrise/Sunset prediction - for any location on Earth - as a free service (for the moment!). Supply the longitude and latitude of your location, the week, and the time zone, and give us a ring. We can give you the results over the telephone or by fax.

The chart is also available via the internet (this is not yet an automated service).
