The Moon phase shown by the Moon graph
is the approximate shape of the Moon at
noon of the displayed date. It is meant only
to indicate whether the left or right side of
the Moon is shaded. Its shape is different
from the actual phase of the Moon.
●
The Moon phases shown in the above table
are for when the Moon is viewed towards
the south with respect to the northern
hemisphere. In the Southern Hemisphere or
near the equator, the light and dark portions
of the Moon are opposite those shown by
the watch’s indicator.
