How to hide/remove the clock from the menu bar of Ubuntu 20.04?
Solution 1:
I am also working on ubuntu 20.04.
Please install gnome-tweaks: sudo apt install gnome-tweaks gnome-tweak-tool. After that open the application gnome-tweaks and choose top bar from the left list, then you can customize your head bar.
This gives you opportunity to customize your date and weekday, but if you wants to remove the clock totally you would need to install further extensions, see if https://extensions.gnome.org/extension/1110/hide-clock/ helps.
