SMF 2.1.6 Calendar events -problem with events created for January dates

[rockyr1156]

SMF 2.1.6 Calendar events - problem with events created for January dates automatically changed to March as the month. e.g. I set 24/01/2026 and it is automatically changed to 24/03/2026. It does this for any year and only in January.

Has anyone got a solution to fix this?

Can not replicate the issue.

1- go to calendar
2- add event
3- add event name
4- add event date (set to 24-January-2026)
5- a- add link to post
   b- without link to post
(if 5a, then create post as normal)
click submit


expected results: event created with date 24-January-2026
actual results: event created with date 24-January-2026

I did everything on your list; however, when I click on the date 24-January-2026 it fills the Start field with 24 Mar, 2026. This has been reported to me by several of my forum members and when I tried the same error occurred.

Check Themes/default/languages/index.{LANG}.php

I seem to remember there was some issue with some language packs where this was wrong, so it might simply be the name of the month that is wrong, not the actual month.

Months:

And a couple of rows past it for different version of the names.

What is the default language for the forum?

The default date format?

Thank you, I found the error in index.english_british.php. All it was, instead of saying 'Jan', it said 'Mar'. A simple

$txt['months_short'] = array(1 => 'Mar', 2 => 'Feb', 3 => 'Mar', 4 => 'Apr', 5 => 'May', 6 => 'Jun', 7 => 'Jul', 8 => 'Aug', 9 => 'Sep', 10 => 'Oct', 11 => 'Nov', 12 => 'Dec');

I changed it to:

$txt['months_short'] = array(1 => 'Jan', 2 => 'Feb', 3 => 'Mar', 4 => 'Apr', 5 => 'May', 6 => 'Jun', 7 => 'Jul', 8 => 'Aug', 9 => 'Sep', 10 => 'Oct', 11 => 'Nov', 12 => 'Dec');

A note:  This is, in fact, an issue with the language packs for english_british & english_pirate.

I went in & changed those two.  I think.
