The moon has eight phases not four as do all other planet combinations and this is where pom from bsd along with most moon phase programs got it wrong. That's what happens when programmers didn't study enough astrology though.

[...] the lunar phases show up in calfw, but for some
reason the time is displayed twice, like so:

    19:48 ? q1? 7:48pm (PDT)
    14:40 ? Full 2:40pm (PDT)
    12:46 ? New 12:46pm (PDT)

I think what's going on is that each phase is considered an event
which somehow gets prefixed with its time in 24hr format...

I'm wondering if this issue may be related to this post on emacs-devel:

 calendar/diary/appt: diary-lunar-phases should not create appointments

   Hi,

   I have

   &%%(diary-sunrise-sunset)
   &%%(diary-lunar-phases)

   which results in emacs nagging me about moon phases and sunsets.
   I don't think this is right: I want to be able to see the times when the
   lunar phases and sunsets happen (and, btw, moon rises and moon sets, but
   they are not available), but I do not want to do anything when they
   actually do happen.

   Is there a way to prevent some diary entries containing times from being
   interpreted as appointments?

no resolution...picked up again a few years later:

... still no resolution.
