Change Gnome and Unity week start day

If you have installed the United States language version of Ubuntu, for sure you have your start week day set to Sunday, instead of Monday, at your calendar applet. There isn’t an option where the user can change this in an user-friendly way, and there are a lot of non-US users (like me) who are used to see the week starting by Monday. This little HOW-TO will show you the way to change it step by step.

  1. Open your favorite terminal application, and edit the file /etc/default/locale
    pedro@pedro-laptop:~$ sudo nano /etc/default/locale
  2. You will se one line containing LANG=»en_US.UTF-8″. Now you have to add the following lines, without removing the first one:
    LC_TIME=»en_GB.UTF-8″
    LC_PAPER=»en_GB.UTF-8″
    LC_MEASUREMENT=»en_GB.UTF-8

    Save the file and exit the editor. With these options, Ubuntu will display the time format in the english european variant, set the default paper size to A4 and set metrics for use with measurements.

  3. In order to start using the new configuration you should restart your graphic desktop manager. Just type this:
    pedro@pedro-laptop:~$ sudo /etc/init.d/gdm restart
Take care! Executing the last command will restart your gdm, and will close all running applications. So please, be sure to save your work before doing this.
