Subtracting days in apex classes

Hi,

 

I have a requirement to find the Friday of this week and then find the Friday before 13 weeks. How can I do that. To find the current friday I did the following

 

this.dateView.Pack__Start_Date__c = date.today().toStartOfWeek().addDays(6);

 

Now how can I get the 13 week before date? as there is no date subtraction function here. So please tell me how can it be done in Apex classes

then i guess this should work....

 

 addDays(-91)....this will take care of leap year....as it only counts the days.... i dont know whether there is any other way.... but you may go on to explore and please let me know if it is posssible by some other way...

But I need the date 13 th week before not 13 days before...except subtracting 91 days(13*7) is there any other way.. this logic should also take care of leap year condition for 29th Februray as well..
