If you like to use only ksh builtin without external gnu date command, then
Code:
#!/bin/ksh93
today=$(printf "%(%#)T" now   )   # epoc  
# or today=$(printf "%(%s)T" now   ) 
(( week=60*60*24*7 ))
(( prevweek=today-week ))
# convert int to datestr, attributes is same as in date command
printf "%(%a %d %b)T\n" "#$prevweek"
