In this repositiry we present the corrected (translations for Persian Language), RTL style and shamsi (hijri) calendar of nextcloud 19.0.1, Hope this contribution suits your needs.

This project is ready to install version, to facilitate the installation process, you can use the default naming used in config file as yours, 'dbname' => 'cloudvir_cv', 'dbuser' => 'cloudvir_cv', as it is obvious in above, you need to create a database and user by the name of 'cloudvir_cv'.

it is crucial to use the Forced language and locale Options in config.php as 'fa' to calendar and styling show correctly.

for best experience I suggest to follow along the Linux Babe tutorial on how to install LAMP and nextcloud in the flowing links:

https://www.linuxbabe.com/ubuntu/install-nextcloud-ubuntu-20-04-apache-lamp-stack

https://www.linuxbabe.com/ubuntu/install-lamp-stack-ubuntu-20-04-server-desktop

but instead of downloading the nextcloud project from the nextcloud server, use the files in this project, in addition there will be a builded and ready version of calendar 2.0.3 of nextcloud in the repository of it's own. (which is Fully PERSIAN and Shamsi (date picker is shamsi as well))

this link : https://github.com/dev-am1/calendar2.0.3_Builded_READY_TO_USE

and the source code will be in the sourcecode repository . this link :
