Sun Angle Calculator

How to use the Sun Angle Calculator

1. Fill in the values you know. Fields already contain typical example values that you can overwrite.
2. Pick the unit for each measurement with the selector beside the field; changing a unit converts the number for you.
3. Leave blank the value you want to find, or simply read the results panel, which updates as soon as there is enough information.
4. A value the calculator worked out is shaded in its field. Type over it to switch which quantity is calculated.

If a value is missing or does not make sense, the field shows a short message explaining what to fix.

Formulas used

This calculator is built on the following relationships between its quantities. Each one can be solved for any of the values it contains, which is why you can leave any single field empty and have it calculated from the others:

time_zone_offset = time_zone + summer_time

elevation = getElevationAngle(latitude, longitude, date_time, time_zone_offset)

azimuth = getAzimuthAngle(latitude, longitude, date_time, time_zone_offset)

Interpreting your results

Once you’ve clicked ‘Calculate’, you’ll receive output that indicates the sun’s position:

• Altitude Angle:

  This tells you how high the sun is in the sky, measured in degrees. An altitude of 0° means the sun is on the horizon, while 90° indicates it’s directly overhead.

• Azimuth Angle:

  This indicates the compass direction from which the sunlight is coming at that moment, measured in degrees from North (0°). For example, an azimuth of 180° indicates the sun is in the south.

Common mistakes when using the Sun Angle Calculator include:
