807635 - Thunderbird does not support the Jalaali calendar

Status: RESOLVED DUPLICATE of bug 254443

(Calendar :: General, defect)

Description

[Philippe Vouters]

User Agent: Mozilla/5.0 (X11; Linux i686; rv:15.0) Gecko/20100101 Firefox/15.0.1
Build ID: 20120911180625

Steps to reproduce:

I file this wish in respect to the Jalaali (Persian) calendar traditionally used in Iran (in Afghanistan ?) which ought to not be handled by Thunderbird in the name of an Iranian contact of mine. As per his mail, Thunderbird in Iran should only be proposing the Hijri (Islamic) calendar.

If Thunderbird developers need Jalaali (Persian) calendar handling relevant code, they may refer to http://vouters.dyndns.org/tima/Linux-Calendars-Internationalizing_dates.html. Being French, I asked my Iranian contact to approve both the Arabic and Persian ways to write a daytime in local format.

If Thunderbird can take into account national specifities, this would be a great plus for Thunderbird. Thunderbird is my current mail/calendar facility. I currently feel quite happy with Thunderbird.

If this Iranian contact is good willing, he may become a local beta calendar tester contact for Thunderbird upcoming version which would handle the Persian calendar.

Dear Thunderbird developers,

As an additional information, the Jalaali (Persian) calendar ought to also be of common usage in Afghanistan and Kurdistan as per this URL link at http://www.calendarhome.com/converter/. Details upon the Persian calendar can be found at http://www.fourmilab.ch/documents/calendar/.

Would my paper at already mentioned URL that I just updated be of any help to Thunderbird developers along with the REFERENCES section it contains, will be a great honour for me.

With my deepest regards to Opensource code contributors.

Please clarify if you refer to date display in Thunderbird itself ( e.g. in the mail list view) or to date display in the Lightning calendar extension. In the latter case it's a duplicate of Bug 254443. Don't know if there already exists a bug too for Thunderbird / Gecko date display.

This does indeed looks as a duplicate of https://bugzilla.mozilla.org/show_bug.cgi?id=254443 as, as suggested by this "bug" report, all my code also bases itself onto the Unix origin date (1900/01/01 for tm_mday = 1; tm_mon = 0; tm_year = 0). As indicated by this "bug" duplicate and as far as I understand things, libical should be used by Sunbird's calDateTime as well as by Lightning as per http://forums.mozillazine.org/viewtopic.php?f=29&t=2468639. I seem to observe with the reading of http://doxygen.db48x.net/mozilla-full/html/df/d51/namespacecal.html
that libical methods belongs to Mozilla's namespace. I got all citadel (another opensource code; a mail/calendar server) used functions prototypes while querying Google and landing to this Mozilla's URL just given. citadel code is strongly based upon libical for all its Calendar management. I am not yet an in-depth expert in Thunderbird to actually distinguish whether calendars operations belong to the Lightning code itself or Thunderbird itself.

Yours very sincerely,

Dear Stefan,

I believe I can now accurately answer your question and this would match my Iranian contact concern. My contact in Iran is specifically looking after a Persian CALENDAR. The word CALENDAR is indeed important. My Thunderbird has just the Lightning add-on activated. I restarted my Thunderbird with all add-ons deactivated. It happens then that I benefit from strictly NO calendar facility. The Event and task pull-down menu where I can display the calendar from has even disappeared in such case.

In consequence, the wish for the Jalaali (Persian) calendar expressed by my Iranian contact solely applies to the Lightning Thunderbird's add-on. I am strictly unable to test and check whether this Jalaali calendar is already implemented in the Lightning add-on. My Iranian contact wrote me that he default benefits from the Islamic calendar which is NOT the common calendar in use in Iran.

If the Persian calendar is already implemented inside Lightning, would someone knowledgeable and kind enough to tell how to Lightning select the Persian calendar instead of its Islamic (Hijri) default ? If already implemented, this could be eventually related to a user selected locale as I do notice that Lightning displays my calendar using pure French words.

Thank you in advance.

Dear Stefan,

Is there any way to ONLY download the Lightning source code. I am good willing to spend some efforts onto to implement the Persian calendar, eventually the Islamic calendar if not yet already implemented.

I can't succeed to find how to only select the Lightning source code for download while navigating onto Mozilla's Web pages. Would you be so kind as to guide me ? I shall cooperate with Alireza who is my actual Iranian contact I did not name so far. Alizera just added its input to this "bugzilla".

Thank you so much in advance for your reply.

With my warmest regards to you.
