EDATE is a DAX function that returns a date shifted by a specified number of months from a start date.
EDATE(
StartDate,
Months
)| Argument | Properties | Description |
|---|---|---|
| StartDate | A date in datetime format that represents the start date. | |
| Months | The number of months before or after start_date. |
A date (datetime).
In contrast to Microsoft Excel, which stores dates as sequential serial numbers, DAX works with dates in a datetime format. Dates stored in other formats are converted implicitly.
If start_date is not a valid date, EDATE returns an error. Make sure that the column reference or date that you supply as the first argument is a date.
If months is not an integer, it is truncated.
When the date argument is a text representation of the date, the EDATE function uses the locale and date time settings of the client computer to understand the text value in order to perform the conversion. If the current date time settings represent a date in the format of Month/Day/Year, then the following string “1/8/2009” is interpreted as a datetime value equivalent to January 8th of 2009. However, if the current date time settings represent a date in the format of Day/Month/Year, the same string would be interpreted as a datetime value equivalent to August 1st of 2009.
If the requested date is past the last day of the corresponding month, then the last day of the month is returned. For example, the following functions: EDATE(“2009-01-29”, 1), EDATE(“2009-01-30”, 1), EDATE(“2009-01-31”, 1) return February 28th of 2009; that corresponds to one month after the start date.
This function is not supported for use in DirectQuery mode when used in calculated columns or row-level security (RLS) rules.
The following example returns the date three months after the order date, which is stored in the column [TransactionDate].
= EDATE([TransactionDate],3)
