Parameters

TermDefinition
datesA column that contains dates.
start_dateA date expression.
number_of_intervalsAn integer that specifies the number of intervals to add to or subtract from the dates.
intervalThe interval by which to shift the dates. The value for interval can be one of the following: year, quarter, month, day

A table containing a single column of date values.

  • 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.

Constraints on Boolean expressions are described in the topic, CALCULATE Function (DAX).

If the number specified for number_of_intervals is positive, the dates are moved forward in time; if the number is negative, the dates are shifted back in time.

The interval parameter is an enumeration, not a set of strings; therefore values should not be enclosed in quotation marks. Also, the values: year, quarter, month, day should be spelled in full when using them.

The result table includes only dates that appear in the values of the underlying table column.

This DAX function is not supported for use in DirectQuery mode. For more information about limitations in DirectQuery models, see http://go.microsoft.com/fwlink/?LinkId=219172.
