Thanks for your reply i mean to say that,

There's no "number of week" calculation in the date function, unfortunately.

You could get a rough approximation with this:

say (date('D','20110114','S')+4)%7

which is nothing else than a rounded integer division of the number of days elapsed in the year by seven.

The format of the second parameter is determined by the third parameter, sou you could as well do:

say (date('D','14 Jan 2011','N')+4)%7

Why did you give a grade "B" then?
