This week and Last week set criteria when week starts on Monday?

This week and Last week set criteria when week starts on Monday?

I live in a country when weeks starts on Monday.
For Last week I applied this set criteria
  1. (Added_Time >= zoho.currentdate.subDay((zoho.currentdate.getDayOfWeek()  +  6)) && Added_Time <= zoho.currentdate.subDay(zoho.currentdate.getDayOfWeek()))
For This week I applied this set criteria
  1. (Added_Time >= zoho.currentdate.subDay((zoho.currentdate.getDayOfWeek()  -  1)) && Added_Time <= zoho.currentdate.addDay((7  -  zoho.currentdate.getDayOfWeek())))
This scripts work when weeks starts on Sunday. How should I modify this set criteria when weeks starts on Monday?
 
Thanks anyone who can help!
