Last friday date

simone pilozzi
Dear users,
I am testing the covariances/corr methods on weekly observations. 
Is there an date function to get the easily the last friday date before a given date t?
Thanks in advance.
Simone

Date::nextWeekday(d, Friday) returns the next friday.  From that, you
can easily get the last :)  Remember to take care of the case in which
the date _is_ a Friday.
