Hi,
I would like to increment the week number by 1 every 7 days, starting from Apr 4 to "some end date".

Thanks in advance!
I have to assume you made a slight error in your post and that April 18 would increment to week=3. Here's a statement you could add to your DATA step:
week = 1 + int( (date - '04apr2014'd) / 7);
Good luck.
