Well, if that represents your source data, you can do this with a calculated column using EARLIER and the technique here:
See my article on Mean Time Before Failure (MTBF) which uses EARLIER: http://community.powerbi.com/t5/Community-Blog/Mean-Time-Between-Failure-MTBF-and-Power-BI/ba-p/339586
Now, that's a pretty nasty format for week though, you'll have to parse it with something like VALUE(RIGHT([WW]),2))
