Several people today asked me what week number to use for network. Apparently, no-one was available at network to answer the question.
There is some confusion on whether today was week 52 for 28/12/2009 or week 1 if dated from today.
Network return weeks start from 1st January; on the 1st January, they get reset. We are now in network week 1.
For this year, network week will be Friday to Thursday.
