Are you open to using datecalc? This will do the job, but you will have to wrap the script in another script of your own.

In your script, just check if day is Friday or Monday. Then accordingly call datecalc with the correct +/- parameters. If not, just call datecalc with +1 and -1 to get tomorrows and yesterday's date. You can check the datecalc script for more help.

All you really need is a couple of arrays with the offsets. I also have started using an array to store dates in y m d format.

Code:

$ set -A Prev -- -2 -3 -1 -1 -1 -1 -1
$ set -A Next 1 1 1 1 1 1 3 2
$ set -A today $(date "+ %Y %m %d")
$ echo ${today[*]}
2007 08 15
$ datecalc -d 1961 1 1
$ datecalc -a ${today[*]} + ${Prev[$(datecalc -d ${today[*]})]}
2007 8 14
$ set -A today 2007 08 13
$ datecalc -a ${today[*]} + ${Prev[$(datecalc -d ${today[*]})]}
2007 8 10
$ cal
    August 2007
 S  M Tu  W Th  F  S
          1  2  3  4
 5  6  7  8  9 10 11
12 13 14 15 16 17 18
19 20 21 22 23 24 25
26 27 28 29 30 31
