#!/usr/bin/gawk -f

BEGIN {

    first=mktime(ARGV[1] " 01 01 00 00 00")

    last=mktime(ARGV[2]+1 " 01 01 00 00 00")

    if (ARGC == 4) { num=ARGV[3] } else { num=1 }

    ARGC=1

    range=last-first

    srand(sprintf("%d%06d", systime(), PROCINFO["pid"]))

    for (i=1; i <= num; i++) {

        print strftime("%d/%m/%Y", range*rand()+first)

    }

}

For example:

./randomdate.gawk 1987 2017 6

26/04/1992

28/04/2010

21/04/2005

17/02/2010

06/10/2016

04/04/1998
