PARALLELPERIOD DAX Function (Time Intelligence)  Context Transition

Returns a parallel period of dates by the given set of dates and a specified interval.

Syntax

PARALLELPERIOD ( <Dates>, <NumberOfIntervals>, <Interval> )
Parameter Attributes Description
Dates

The name of a column containing dates or a one column table containing dates.

NumberOfIntervals

The number of the intervals.

Interval

One of: Day, Month, Quarter, Year.

Return values

Table A table with a single column.

A table containing a single column of date values.

Remarks

The dates argument can be any of the following:

  • A reference to a date/time column. Only in this case a context transition applies because the <Dates> column reference is replaced by
  • 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.

This function takes the current set of dates in the column specified by Dates, shifts the first date and the last date the specified number of intervals, and then returns all contiguous dates between the two shifted dates. If the interval is a partial range of month, quarter, or year then any partial months in the result are also filled out to complete the entire interval.

The result table includes only dates that exist in the dates column.
