Functionalities
The month and date are
C
displayed at the 9 o'clock
position.
The moon phases are shown
D
three dimensionally at the
6 o'clock position. If the Moon
is completely black, then it is
new moon. This is followed by
the waxing moon up to the first
quarter, with the right-hand
side of the Moon visible. After
that, the full moon is displayed,
followed by the waning moon
up to the last quarter, with the
left-hand side of the Moon
visible. The lunar cycle ends
with the new moon, and then
starts again at the beginning.
The dial at the 3 o'clock
E
position shows whether a total
or partial solar or lunar eclipse
is possible anywhere in the
world. The eclipse hand is then
vertical in the striped section.
A solar eclipse only occurs if
there is a new moon.
A lunar eclipse only occurs
if there is a full moon. If the
eclipse occurs when the Moon
is at the ascending node, the
red arrow on the eclipse hand
points upwards. If the Moon
is at the descending node, the
red arrow on the eclipse hand
points downwards.
The declination is shown at the
F
12 o'clock position. The Earth is
at an angle of 23,5˚ compared
to the Sun. As a result of this
axial tilt, the number of hours
of sunlight varies, which is why
we have seasons. The maximum
value of the declination indicator
is shown on the longest day
(21 June). When the declination
is lowest, this is the shortest day
(21 December).
