Start the week on Monday in the Clock applet in Ubuntu

Question

When clicking on the Clock applet (Clock version 2.26.0) in Gnome (Ubuntu Jaunty) a calendar is shown. Each week starts on Sunday, but I want Monday as starting day. How can I achieve this?

Answer 1

this depends on your locale.

you need to check LC_TIME change first_weekday from 1(sunday) to 2(monday)

i just googled and this seems quite a comprehensive guide:

1. Make a copy of your locale file in your home directory
   cp /usr/share/i18n/locales/en_US ~/en_US_modified

2. create a directory "locales"
   mkdir ~/locales

3. open up en_US_modified in an editor, search for the section called "LC_TIME"

4. look for the line
   first_weekday 1

5. Change the 1 to a 2

6. Save the file, exit your editor and go back to the terminal

7. Run this command which will create a directory full of new locale settings inside of the "locales" directory you made in your home directory:
   localedef -c -i ~/en_US_modified -f UTF-8 ~/locales/en_US.utf8

8. Backup your old locale settings by going to /usr/lib/locale and changing the name of
   en_US.utf8 to en_US.utf8_ORIGINAL
   
9. Copy the new en_US.utf8 directory your created in your home directory in the subdir "locales" to /usr/lib/locale
10. Restart your system

Answer 2

Just set LC_TIME to a locale that starts its week on monday. eg: LC_TIME=en_GB.UTF-8

Make that change permanent by editing /etc/default/locale (or /etc/locale.conf on some distros)

The best way is to set your locale is on a per user setting, for example in gdm at login. If there is a specific need for more complex things, you can set the locale in /etc. Note that this will affect all users on the system.
