How to change time and date language to English?

I do not know how it comes, but my calendar(upper right corner) is in Polish. How to change this to English?

Solution 1:

If everything except date is in English, then there is a high chance that the value of LC_TIME is something wrong, use localectl command to change it to your desired locale:

sudo localectl set-locale LC_TIME=en_US.utf8

or en_GB.utf8 for UK.

You can also place LC_TIME=en_US.utf8 at this file /etc/default/locale manually if you wish.

Solution 2:

data utility uses variable LC_TIME to know what language of days to use. If you want to know if this is really the issue, try:

echo $LC_TIME

then if you dont want to mess up anything, but still have different language in your script just change it in your script like

LC_TIME=en_US.utf8

Solution 3:

The default locale file location here: /etc/default

First install: nautilus-admin then logOut and logIn.

Then go to /etc/default.

Right click on locale and Edit As Administrator.

Edit locale file like this and save:

#  File generated by update-locale
LANG="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"

Done. Now log-out and log-in.
