Lunar Phases in Calendar

Lunar Phases in Calendar

[Christopher Dimech]

Is it possible to highlight the Lunar Phases in Calendar.
How can I include a command in my emacs init file?

It is all possible, only it may not be easily customizable.

Please explain what exactly you wish to have in the configuration?

Side notes:

As we are on different parts of the planet I think, but I am not so
sure, that {M-x lunar-phases RET} could require latitude and
longitude.

(setq calendar-latitude -1.12484)
(setq calendar-longitude 29.72780)
(setq calendar-location-name "Bwindi Impenetrable Forest")

You would need something like that in your ~/.emacs or
~/.emacs.d/init.el 

You may want to setup your calendar time zones as well.

(setq calendar-standard-time-zone-name "EAT")
(setq calendar-time-zone 180)

Inspect those variables by moving with the cursor to variable and
pressing {C-h v}

Re: Lunar Phases in Calendar

I have written the following commands in my init file.
But when I go in calendar and hit 'x', the date for
'First Quarter Moon' is not highlighted.

(require 'calendar)
(setq holiday-solar-holiday
   '((holiday-fixed 11 22 "First Quarter Moon")) )
(calendar-mark-holidays)

I can see typo, it should be `holiday-solar-holidays'

AFAIK earth is too small for exact position on earth to have an effect
(unless Bwindi Impenetrable Forest has its own moon).

Re: Lunar Phases in Calendar

[Christopher Dimech]

Does anyone know how to set new holidays so they get marked
after hitting 'x'.

I was just guessing program is using those to calculate it more
correctly as related to time zones. For somebody in Seattle, WA it
will be maybe 10-14 hours back and previous date, somebody will have
it next day, all in same time. I did not look into calendar inside,
not yet. It is interesting to have those in Emacs.

I remember two clients arrived from US and have seen calendar on my
Emacs and have been wondering how is possible to have all those
features in the same software. They did not know what is Emacs.

M-x package-install RET german-holidays RET

Then in the ~/.emacs.d/elpa/german-holidays-* folder find how it looks
like, inspect it.

Then make your own.

How do you want them to be highlighted?

Michael.

Re: Lunar Phases in Calendar

[Christopher Dimech]

Currently, when I am in Calendar and hit 'x' I get brown highlighting.
But for my new moon phase T get nothing, as though nothing happens on
that date.

Somewhat my comment is going to be off-topic, sorry...

The Lunar is very very complicated. In particular, "Chinese New Year"
and "Korean New Year" is different in Lunar calendar.

Not Complicated.  Just a ball rotating.

That depends on whether you're talking about the
moon itself (then "a ball rotating" is a pretty
good approximation indeed, although, if you look
closely, you're into N-body problems, but I don't
have to tell that to /you/, I think ;-)

Or whether you're approaching it from the viewpoint
of human calendars, trying to make sense of several
incommensurable (and not really constant) observational
constants (solar day, solar year, lunar month) and
to try to fit them into each other. There, the human
creativity has been impressive indeed :-)

So those kinds of "calendars" are, as Byung-Hee politely
puts it, "complicated".

Trying to fit people's calendar together?  Impossible.  Stick with the moon

Then of course, you've got lunar mansions used in India for timing.  But
emacs can't even get the 8 phases right so all of this may be better
done using external software and pasting its results into an emacs
buffer.  For those with any interest, a phase  has a 45 degree angle not
a 90 degree angle.

Thanks. Could you find references for that?

If it is not correct in Emacs, could you please find the reference and
{M-x report-emacs-bug RET} with such?

[Jude DaShiell]

I have a contact in for that source, probably will be in form of an url
possibly with printed book references.  I don't read printed books since
my first reading language by absolute necessity was braille.

Alright. It is first time for me to even think about the moon phases.

Wikipedia reference:
https://en.wikipedia.org/wiki/Lunar_phase#Phases_of_the_Moon

They reference 4 principal lunar phases so those are by 90
degrees. Then there is reference to intermediate phases thate are
between those principal lunar phases. In that sense I understand it.

It is play of light.

What I know about the moon is that chasing elephants with moonshine
back to Bwindi Impenetrable Forest helps when running through the wet
land.

N.A.S.A. is not a credible authority on Astrology.  They do fine with
Astronomy but that's the limit of their knowledge and capability.
