A table containing a single column of date values.

Note
To understand more about how context affects the results of formulas, see Context in DAX Formulas.

The dates argument can be any of the following:

• A reference to a date/time column.

• A table expression that returns a single column of date/time values.

• A Boolean expression that defines a single-column table of date/time values.

Note
Constraints on Boolean expressions are described in the topic, CALCULATE Function.

The following sample formula creates a measure that calculates the 'Quarterly Running Total' of the internet sales.

To see how this works, create a PivotTable and add the fields, CalendarYear, CalendarQuarter and MonthNumberOfYear to the Row Labels area of the PivotTable. Then add a measure, named Quarterly Running Total, using the formula defined in the code section, to the Values area of the PivotTable.

=CALCULATE(SUM(InternetSales_USD[SalesAmount_USD]), DATESQTD(DateTime[DateKey]))
