You can determine your location in different ways:
• You find a table with the coordinates of all US counties in
the chapter ”Position Table”. Select a town close to you
and enter its coordinates.
• If you possess a GPS navigation device, e.g. in your car
or a mobile one, you can take over its location information
and then you have your exact position.
• You can also get the exact coordinates via the Internet.
It provides numerous pages which contain information on
navigation.
Please consider the fact that the data for sunrise or sunset
are only exact at the sea or for a totally even landscape. Hills,
high forests etc. alter these values for your location.
Even for ideal positions the data may vary by some minutes,
because an approximation formula is used for the calculation.
