How to change date format?

Hello, how I can change date format?
Example Course starts - 1 oct. 2020 06:00 +06.
How to make Course starts - 1.10.2020
Thanks

In /edx/app/edxapp/edx-platform/conf/locale/en/LC_MESSAGES/django.po change below lines to desired date format

LONG_DATE_FORMAT
DATE_TIME_FORMAT
SHORT_DATE_FORMAT
TIME_FORMAT

for example:

msgid "LONG_DATE_FORMAT"
msgstr "%A, %B %d %Y"

then run below lines to create .mo file from .po file

python manage.py lms compilemessages
python manage.py cms compilemessages

and finally restart lms and cms by this command:

sudo /edx/bin/supervisorctl restart lms
sudo /edx/bin/supervisorctl restart cms
