To use, import this module into ~/.xmonad/xmonad.hs:

     import XMonad.Actions.SimpleDate

and add a keybinding, for example:

    , ((modMask x,               xK_d     ), date)

In this example, a popup date menu will now be bound to mod-d.

For detailed instructions on editing your key bindings, see XMonad.Doc.Extending#Editing_key_bindings.
