Changing The Date And Time
When you open Starry Night, you may see
a bright blue sunny sky, a dark sky filled
with stars, or a twilight realm with only a
few bright stars showing. This is because
Starry Night always opens showing the
sky at the current date and time. The date
and time are shown in the upper left corner
of the toolbar.
Tip: A small icon of the Sun
appears to the left of the time in the
toolbar. If Daylight Saving Time is
turned on, this icon is lit up. Starry Night
uses your computer clock to determine if
Daylight Saving Time should be turned on.
Click on the icon to turn on or off Daylight
Saving Time.
See “How does Daylight Saving Time
work in Starry Night?” on page 192 for
more information on Daylight Saving
Time.
To change the date or time, just click on it.
The date or time will light up, and you can
type in a new value.
If Starry Night is showing a daytime
scene, try changing the time so that it is
night. If you already see a night scene,
change the time so that it is day. Starry
Night allows you to set the date from
anywhere between 4 713 B.C. and 3 000
A.D. for CSAP, 4 713 B.C. and 9 999 A.D.
for Enthusiast, 99 999 B.C. and 99 999
A.D. for Starry Night Pro and Starry Night
Pro Plus.
Immediately below the Time and Date
control is a set of 3 buttons that allow you
to reset the time to the current time or
quickly change the time to sunrise and
sunset.
Tip: As you are working through the rest of
the features in this chapter, you will
probably want to set the time in Starry
Night so that the sky is dark. In the day,
only the Sun will be visible onscreen, and
it will be difficult to use some of the
features.
Special Times:
Immediately to the
right of the time
display in the toolbar is
a pull-down menu that
lets you quickly change
the time to one of
several key times.
You can reset the time to the current time
by pressing Now or set the time to sunrise,
sunset, moonrise or moonset. You can also
change to
solar noon, the time at which the
Sun is highest in the sky, or
moon transit,
