Sun Calendar
 












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

    • 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.
    • 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.

Moon Calendar
 












On the Moon Calendar display (above), the calendar will indicate the days for new moon, first quarter, full moon, and third quarter, at the computer's location, considering daylight savings time if it is in effect.  In addition, to the right of the calendar you will see:

    • The time and direction (clockwise from true north) of moonrise and moonset.
    • The current phase of the moon.

On both calendar screens, the calendar is an active input device.  Click on a day of the month to recalculate the display for the date clicked upon.  Click on a month to select the new month.  Click on the year before or the year ahead to go back or forward a year.  Worldclock will keep the new date you selected as you go to other screens.

If you change the date using either sun or moon calendar, WorldClock 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 WorldClock.
