#244101 — /usr/share/calendar.usholiday

There's a stale version of this file on my system that reflects
when Debian was installed but it brings a question to mind.

	Does this file simply cause messages to appear on an
event calendar or can it be used along with crontab in some way
to either cause or prevent cron jobs from running if a date
matches one of the dates in the file?

	I use cron and at jobs all the time and have thought that
it would be nice to skip some jobs if the day is a holiday and
the result might be not what one wanted.

	Right now, I don't think this file is doing a thing as it
is for 2017 but this is why I am asking.

	I also saw versions of that file for other countries such
as the UK.

	Thanks for all good responses.

The one in the Subject: header?  Are you sure that's the correct
path for this file?

On Debian 11, I have the file /usr/share/calendar/calendar.usholiday
which is a different path from the one you showed.

unicorn:~$ ls -ld /usr/share/calendar/calendar.usholiday 
-rw-r--r-- 1 root root 1418 Mar 23  2021 /usr/share/calendar/calendar.usholiday
unicorn:~$ dpkg -S /usr/share/calendar/calendar.usholiday 
calendar: /usr/share/calendar/calendar.usholiday

I'd imagine it's used by the "calendar" program in the calendar package.
The string "calendar.usholiday" appears in the calendar(1) man page, in
an example, as well as in the FILES section.

What version of Debian are you using, and where do you see 2017?

And if you look into the file, you see it has no years associated with the
date, so it doesn't matter when it was written unless there was a change in
the official holidays in the US.

	Correct.  I see two types of date references, exact dates
such as Christmas and New-year's and rule-based dates which are
some designated day such as the second Monday in a given month,
what the British refer to as a "bank holiday."

	My original question about this file has been answered in
a round-about way in that there are also two types of holidays.
St. Valentines day, for example, is not a postal or bank holiday
but one will certainly get in deep trouble on the home or
romantic front if that day is forgotten.

	Also days like Arbor Day are a nice idea but nothing
about normal commerce or daily activities changes

	I also noticed that today in the United States should be
marked but hasn't been yet.  It is the third Monday in January
which, since 1986 has been the official recognition of
the birthday of a US civil rights leader, Martin Luther King Jr.

	The entry in that file probably should read:

01/MonThird	Martin Luther King Birthday (3rd Monday of January)

	It is now a major holiday and schools and government
offices are usually closed so it should probably be there.

	Thanks to all and sorry if I created  any confusion about
the path.

Martin McCormick.

unicorn:/usr/share/calendar$ grep Luther *
calendar.birthday:01/15	Martin Luther King, Jr. born, 1929
calendar.birthday:11/10	Martin Luther born in Eisleben, Germany, 1483
calendar.history:04/04	Martin Luther King assassinated in Memphis, Tennessee, 1968
calendar.history:08/28	Martin Luther King leads over 200,000 in civil rights rally in Washington, DC, 1963
calendar.history:10/31	Luther nails 95 Theses to door of Castle Church, Wittenberg, 1517
calendar.history:12/01	Martin Luther King Jr., leads black boycott of Montgomery buses, 1955
calendar.holiday:01/MonThird	Martin Luther King Day in New York (3rd Monday)
[...]

So... yes, slightly out of date even on bullseye.  You could file a bug
report if you wish.

	I goofed.  I thought I could remember it long enough but
it is actually


/usr/share/calendar/calendar.usholiday

	I also still had an old directory tree from when I had
wheezy on the system and there is

/home/wheezy/usr/share/calendar/calendar.usholiday

I am presently running

Debian GNU/Linux 10 as in Buster.

That was just a mistake on my part.  Sorry to add more confusion.

	This also reminds me to get rid of the old wheezy files
since I now don't even remember why I saved them but they are
getting backed up nightly for no reason at all other than they
get caught up in the sweep.

Buster was released in the summer of 2019, so it's not totally
unreasonable for one of its packages to have been last updated in 2017.
Especially if there weren't any changes to the official federal US
holidays between 2017 and 2019.  (I have no idea whether that's true;
I don't normally keep track of such things.)
