For most people, the command line option supplied by itnet7 is probably the quickest.
However, if you like a GUI, you can use the tool dconf-editor. Simply run "dconf-editor". It is included by default with many distributions, but should be in the repositories if it isn't installed.
One you've started dconf-editor, follow the tree of settings to: org-gnome-shell-clock
and change the "Show date" checkbox (as shown below), and the seconds display for the clock too, if you like that sort of thing.
Edit: This has changed slightly for Ubuntu 12.10. Using dconf-editor, date & time settings are now located under com-canonical-indicator-appmenu-datetime.
For GNOME Shell 3.30.2 the key is org.gnome.desktop.interface clock-show-date.
REF: How do I show date next to time in the panel with gnome-shell?
Ubuntu 18.04: The tool "dconf-editor" also works GREAT in 18.04, although the location (in the editor) has changed.
dconf-editor is easily added with the included Ubuntu Software app.
Simply search for "date" with deconf-editor's search feature and turn date "on".
As a regular user run this in a terminal when using GNOME Shell:
Not an ubuntu user but, if you install gnome-tweak-tool, you'll have a nice gui to adjust things like this.
I'm guessing your install from repo might be something like:
For Ubuntu 17.10, I found using the
gnome-tweak-tool
to be the most convenient way.Install
gnome-tweak-tool
if not already installed.Start the tool, either from command line,
$ gnome-tweak-tool
or using Dash (tweak
).Select Top Bar from left and then make the necessary changes at right under Clock.

I installed the "Clock override" extension for gnome-shell, which let's you configure how the date and time is displayed. https://extensions.gnome.org/extension/1206/clock-override/
