A year rarely begins on a Sunday or ends on a Saturday and because of this, the last few days of the year fall into a “Week 53” time frame. For example, in the year 2007, December 31st was a Monday and January 1st was a Tuesday. Week 53 will be the last few days of 2007, and Week 1 of 2008 will be the first few days of 2008.
When viewing reports for Week 53 a user will see a weekly report, which only shows December 30 and 31st. The rest of the week will appear to have no data in it. Week 1 of 2008 will show data from January 1st forward, but the prior two days will appear to have no data.
At present, there is no way to automatically get a single report to show the full week.
If combined results are needed from both time frames, Webtrends recommends manually adding the numbers for each time frame to get an entire week. This can be done by exporting the reports for each time frame and manually combining them in a single CSV, or other methods outside of Webtrends.
