Month of year
The 'Month of year' dimension reports the month of any given year as a dimension item. This report is valuable if you want a report broken out by the month of the year, but do not want a static date as dimension items. You can aggregate year-over-year reports by month, so January data of this year aggregates with January data from last year in the same dimension item.
Populate this dimension with data
This dimension works out of the box for all implementations. If a report suite contains data, this dimension works.
Dimension items include months of the year ( January to December ), representing the month of the year that the hit occurred on.
