No calendar.canada, eh?

$ sudo apt install calendar -y

According to man the following files should come with it:

     calendar              File in current directory.
     ~/.calendar           Directory in the user's home directory (which calendar changes into, if it
     ~/.calendar/calendar  File to use if no calendar file exists in the current directory.
     ~/.calendar/nomail    calendar will not send mail if this file exists.
     calendar.all          International and national calendar files.
     calendar.birthday     Births and deaths of famous (and not-so-famous) people.
     calendar.canada       Canadian holidays.
     calendar.christian    Christian holidays (should be updated yearly by the local system administra‐
                           tor so that roving holidays are set correctly for the current year).     Days of special significance to computer people.
     calendar.croatian     Croatian calendar.
     calendar.discord      Discordian calendar (all rites reversed).
     calendar.fictional    Fantasy and fiction dates (mostly LOTR).
     calendar.french       French calendar.
     calendar.german       German calendar.
     calendar.history      Miscellaneous history.      Other holidays (including the not-well-known, obscure, and really obscure).
     calendar.judaic       Jewish holidays (should be updated yearly by the local system administrator
                           so that roving holidays are set correctly for the current year).        Musical events, births, and deaths (strongly oriented toward rock 'n' roll).           New Zealand calendar.

     calendar.ushistory    U.S. history.
     calendar.usholiday    U.S. holidays.        World wide calendar.

Am so so excited that calendar.canada is included that way I can never miss any other of my royals' celebration.

For example by issuing calendar -t 0609 -A 21 -f /usr/share/calendar/calendar.canada I would be querying the CA events for a three-week period. The problem is that this file did not came with the calendar package:

$ ls /usr/share/calendar
calendar.all        calendar.discordian  calendar.judaic       calendar.newzealand
calendar.argentina  calendar.dutch       calendar.judaic.2020  calendar.pagan          de_AT
calendar.australia          calendar.judaic.2021  calendar.russian        de_DE
calendar.belgium    calendar.freebsd     calendar.judaic.2022  calendar.southafrica    fr_FR
calendar.birthday   calendar.french      calendar.judaic.2023  calendar.thai           hr_HR
calendar.christian  calendar.german      calendar.judaic.2024  calendar.ubuntu         hu_HU   calendar.history     calendar.kazakhstan   calendar.ukrainian      pt_BR
calendar.croatian     calendar.lotr         calendar.unitedkingdom  ru_RU
calendar.debian     calendar.hungarian        calendar.usholiday      uk_UA

So my questions are:

  1. What's the easiest way to get this file installed and
  2. Why is UA listed in there but not CA and
  3. Can moving forward /usr/share/calendar/calendar.canada be included into UM versions?



Hi, @DLS (Daniel LaSalle) :slight_smile:

This took me quite a bit of "detective work"! I eventually found a "calendar.canada" in the OpenBSD files.

Later, I can try to explain better my "detective work". But, for now, here's the direct link to the current version of that "calendar.canada" file in OpenBSD:

EDIT: I've just found another copy in the "Read-only git conversion of OpenBSD's official CVS src repository" in GitHub:

And here's the current textual content of that "calendar.canada" file from the first link:

Hello @ricmarques

As usual I really appreciate you picking up the ball and helping me love Linux even more <3

Following the BSD content I went ahead and populated /usr/share/calendar/calendar.canada and tried again but alas it seems that calendar needs to source the file:

$ calendar -t 0612 -A 21 -f /usr/share/calendar/calendar.canada
$ calendar -t 0612 -A 21 -f /usr/share/calendar/calendar.unitedkingdom 
Jun 18*	Father's Day
Jun 18 	Waterloo Day
Jun 24*	Armed Forces Day
Jun 24 	Midsummer (quarter day)
$ ls -l /usr/share/calendar/                      
total 312
-rw-r--r-- 1 root root  1277 Aug  4  2020 calendar.all
-rw-r--r-- 1 root root  6436 Jun 22  2020 calendar.argentina
-rw-r--r-- 1 root root  2416 Jan 28  2022 calendar.australia
-rw-r--r-- 1 root root  2749 Jan 30  2018 calendar.belgium
-rw-r--r-- 1 root root 15664 Jan 28  2022 calendar.birthday
-rw-r--r-- 1 root root  1230 Jun 11 09:56 calendar.canada

What we can see above is the first command pointing to the canada file that failed. Issuing the same command but pointing on a calendar file that was installed with the package worked as we can see on the 2nd command. Lastly we can see that the ownership is the same on all of the files.

Any idea?
