How can you change the calendar language for the weekdays S, M, T, W, T, F, S?

In what way do you want to change them?
—————
The display of them is in your (index) template, looks like this…
{calendar_heading}
  <td class=“calendarDayHeading”>
    {lang:weekday_abrev}
  </td>
{/calendar_heading}
—————
If you are looking for the actual language, it’s probably in the “lang.core.php” file and looks like this…
“Su” => 
“S”,
“Mo” =>
“M”,
etc.

Of course I could also be totally wrong but that’s my guess

I want to change them into Z, M, D, W, D, V, Z (dutch)
It’s not in the template and also not in the core.language.php

Well at last I found it, it’s located in /system/modules/weblog/mod.weblog.php

Hmmm…by golly it is.
Not sure that’s a good thing. Makes it difficult to change your language if things like that are in the actual code. You’d think it should be in the language files and just called from the code (functions).

The date information is included in the language files: lang.core.php, to be exact.

If you download the Dutch language pack then you should be able to use that fine.  You’ll need to set Dutch as your language in your profile: My Account > Localization Settings.

Chris...what is all that day of the week language in the mod.weblog.php (around line 3457) do? Looks like hard coded terms. Is it actually replaced by the language files upon execution?

It’s probably just default values if nothing else overrides it.  I’d have to look through the code to be sure, but the language files definitely have the date/time information in them which is used for the display.

Chris...date/time information in them which is used for the display...Including the headers for the calendar? It kind of sounds from the post that the only way Gnuus got the calendar headers to change was by editing the mod.weblog.php file.
Gnuus...could you verify what worked for you?

Well Chris you’re right it is in the language pack, the only thing was that not everything was translated there. So the editing of the mod.weblog.php file was not necessary.

Thanx.

If not everything was translated, then you might want to do so and send Rick a revised copy of the language pack.  That way others can benefit.
