I do not know how it comes, but my calendar(upper right corner) is in Polish. How to change this to English?
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
en_GB.utf8 for UK.
You can also place
LC_TIME=en_US.utf8 at this file
/etc/default/locale manually if you wish.
locale file location here:
nautilus-admin then logOut and logIn.
Then go to /etc/default.
Right click on
locale and Edit As Administrator.
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.
