st: generate a variable for Project Week

From   Michael McCulloch <>
Subject   st: generate a variable for Project Week
Date   Mon, 27 May 2013 10:29:07 -0700

To generate a variable for elapsed Project Week, I have written the following manual commands, in which the first Project Week is May 6, 2013 through May 12, the second week is May 13 through the 19th, and on forward:

gen week=1 if date>=mdy(5,6,2013) & date<mdy(5,12,2013)  
replace week=2 if date>=mdy(5,13,2013) & date<mdy(5,19,2013)  

Is there a shorter more elegant way to accomplish this?

Best wishes,
Michael McCulloch, LAc MPH PhD
