Changing the calendar changes the way data is processed (i.e. the definition of weekly and monthly unique visitors). When a calendar’s definition of weeks and months changes, historical data is not altered. This setting also affects segments based on date ranges.

You can use the calendar to define the first day of the week and year, or use a different retail calendar style. The calendar formats are used to for various purposes, including sales comparison and forecast standardization, payroll cost analysis, or physical inventory count regulation. For example, the retail industry uses the 4-5-4 accounting calendar to support selling season’s particular to the retail industry. Each of the calendar formats is described below.

Calendar Description

Gregorian Calendar

Uses the traditional calendar format (January through December, with 30 or 31 days and a variable number of weeks in each month).

Modified Gregorian Calendar

Uses the Traditional Gregorian Calendar but enables you to select the first month of the year and first day of the week.

4-5-4 Retail Calendar

Breaks down each month by the number of weeks in the month. Meaning, January has four weeks, and so on. The National Retail Federation uses the 4-5-4 calendar format.

Custom Calendar

Offers three formats based on the number of weeks in each month. The number of weeks in each month depends on the selected first day of the year.

A year has 52 weeks. Divide that into 4 quarters and you get 13 weeks per quarter. But there are 3 months in a quarter. 13 is not divisible by three so you end up putting the extra week into one of the months so that it's always consistent. 5/4/4 means the 1st month of the quarter has the extra week. 4/5/4 means the 2nd month has the extra week, etc. In the 5-4-4 calendar, the 53rd week is added onto the last quarter of the year.

  • 4-5-4:January has four weeks, February has five weeks, March has four weeks, and so on.
  • 4-4-5: January has four weeks, February has four weeks, March has five weeks, and so on.
  • 5-4-4: January has five weeks, February has four weeks, March has four weeks, and so on.

Note: This calendar option is supported across all Adobe Analytics tools (Analysis Workspace, Reports & Analytics, Report Builder, Activity Map) except for Data Warehouse, which does not support custom calendars.
