Why do something just for 'cal' when you can solve the problem once and for
all, UNIX-style?! Below is a highlighting/colorizing search filter that
can be used with both cal or any other strings...

# SEARCH: highlights search expression via sed, can be used with grep
# CAUTION: requires compatible terminal whos highlight/colorization data is
#  available via 'tput' (TERMINFO database). Presumes the availability of
#  the 'setcolor' utility.
#
# Usage: search 'string' < /file/name          (highlights string)
#	 prog | search 'string'                (highlights string)
#        search 'string' /file/name            (highlights string)
#        prog | search -l 'string'	       (highlights whole line)
#
#        prog | search color1 color2 'string'  (uses color instead of inv vid.
#                                               Sets foreground color only.
#                                               'color2' arg should be the
#                                               CURRENT foreground color in
#                                               in use prior to using search)
