Sun Calendar

Choose Sun Calendar from the HourWorld™ Display menu at the top of the screen.

A calendar will be displayed beneath the world map.

 















On the Sun Calendar display (above), to the right of the calendar you will see:

   • The day of the year.
   • The declination of the sun in degrees north or south of the Equator.  The sun stays in 
        a band between the Tropic of Cancer (23.5° north of the Equator) and the Tropic of
        Capricorn (23.5° south of the Equator).
   • The maximum altitude reached by the sun this day, and the time that occurs.  This is 
      the time of apparent (solar) noon at the computer's location.

If you change the date using the calendar, HourWorld™ will ask you if you want to change
the date at the time you close the program or click the go-away box.  If you select "Save",
your system clock will be changed to the new date.  If you have only been experimenting,
or checking on solar conditions for another date, and do not wish your system clock to 
be reset, do not select "Save" upon closing HourWorld™.
