With linux, GNU date should be available, so sth like this might help:
Code:
date -d "-$(($(date +"%u")-1)) days" +"%d/%m/%Y"
13/10/2014

I think that mohanalakshmi wanted to give it a week number as input (41 in the example) and get the days from that rather that just "What are Monday & Thursday this week"


Let me have a think........Smilie

OK, try
Code:
week=39
date -d"-$(($(date +"%u - 1 + 7*(%W - $week)"))) days" +"%d/%m/%Y"
29/09/2014

Oops, my excitement got the better of me in typing a response. I agree that it does give the correct date.
