  Sunrise/Sunset Version 1.5

   Sunrise/Sunset Calculator  was designed 
for Professional Truck Drivers and companies 
that haul oversize and wide loads.  Oversize 
loads are usually only permitted to be hauled 
during daylight hours.  This calculator can be 
used to quickly look up the sunrise/sunset 
times of any town within the United States
by clicking on a state's button and then on 
a town name.  A special 'USER' button can 
be programmed with other locations in 
addition to those already listed in the 
individual states.  Sunrise/Sunset times 
should be correct within +/- 3 minutes.  It 
has only been tested for accuracy within 
the U.S.

I.  N, S, E, and W coordinates can be 
directly entered into the -W'/ E' and 
N'/ -S' coordinate boxes.  The state 
buttons can also be used to look up the 
coordinates of a town.  Click on the 
appropriate state and then simply begin to 
type the name of the town.  The town list 
will automatically scroll as the town 
name is typed.  Click on the town name to 
place the coordinates into the coordinate 
boxes.  (If the town name scrolls to the top 
of the list, you can simply hit enter to place 
the coordinates into the coordinate boxes.)

II.  Next, enter the date of the desired 
sunrise/sunset times. The program always 
starts with the current computer date.

III.  Enter the 'GMT Offset'. The 'Offset List' 
can be used to select an offset. (Professional 
Drivers usually keep their watches on their 
home time for logging purposes.  By selecting 
the GMT Offset for home time, the rise and set 
times for any town will be calculated to a 
driver's home time.)

Other Options:

Lock GMT Offset:  This keep the GMT Offset 
                                  from being cleared after each 
                                  calculation.
Display Military Time:  Sunrise/Sunset times 
                                 are displayed in military time.
Home:   A home sunrise/sunset time can be 
              quickly calculated via this button. 
USER:  USER town/coordinates can be accessed 
              via this button.
Save to USER: Save the currently selected town
             to the USER list. 
LED:    When checked, an LED will flash if the 
             GMT List offset is set to standard time 
            during daylight time or set to daylight time 
            during standard time.
Moon: The phase of the moon is displayed when 
            checked.
