LASTDATE Function (DAX)

Returns the last date in the current context for the specified column of dates.

Syntax

LASTDATE(<dates>)

Parameters

Term

Definition

dates

A column that contains dates.

Return Value

A table containing a single column and single row with a date value.

Remarks

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 (DAX).

When the current context is a single date, the date returned by the FIRSTDATE and LASTDATE functions will be equal.

Technically, the return value is a table that contains a single column and single value. Therefore, this function can be used as an argument to any function that requires a table in its arguments. Also, the returned value can be used whenever a date value is required.

Example

The following sample formula creates a measure that obtains the last date, for the current context, when a sale was made in the Internet sales channel.

To see how this works, create a PivotTable and add the field CalendarYear to the Row Labels area of the PivotTable. Then add a measure, named LastSaleDate, using the formula defined in the code section, to the Values area of the PivotTable.

=LASTDATE('InternetSales_USD'[SaleDateKey])
