I see no bug. -week()- tells you the week 
of the year, and 16 July was in week 30
of 2007. 

However, -week()- does not yield a date
in weeks. If you -format- as if it were 
a date in weeks, then you get the result
that it was in 1960, as Stata starts 
dates on 1 January 1960. 

You don't say what you expected, but 
I suspect you want a quite different function.
