HOWTO: Set Calendar First Day of Week

HOWTO: Set LXDE /and other/ First Day of Week

Here is how to change the gnome calendar first day of the week to Monday.

Check which locale you are using (mine is en_US, don't worry about the .UTF ending):

Code:

locale

Next, backup and edit the applicable locale file (use the result of the previous command if not en_US).

Code:

sudo cp /usr/share/i18n/locales/en_US /usr/share/i18n/locales/en_US.bak
sudo leafpad /usr/share/i18n/locales/en_US

Locate the following line and change the value. The value for Monday in en_US was 2. Select the appropriate number if you desire another day to be the start day.

Code:

first_weekday 2

and 

first_workday 3

Save the file and then:

Update the locales:

Code:

sudo locale-gen

AND

lxpanelctl restart

and OK
