This function will be deprecated in a future release, so use it with caution.

However, it is still supported for existing expressions, so it has not been removed from the application. Editing an expression using this function can cause an error message to appear.

Instead of this function, use BeginningOfDay(-365).

Returns the local date and time for the date that was 365 days ago, based on the local time of the current session.

This is not the same as one year ago, which is always the same month and day, but has a different year.

Return Value

DateTime value.

The return value can be either the same month and day as today (with the year for last year) or it could be one day different, depending on whether there was a leap day in the last 365 days.


If today is April 10, 2014, this function returns April 10, 2013. There was no leap day in the last 365 days.

If today is April 10, 2016, this function returns April 11, 2015. April 10, 2015 was 366 days ago, and not 365 days ago, because there was a leap day (February 29, 2016) in the last 365 days.

If today is January 25, 2016, this function returns January 25, 2015. Even though 2016 is a leap year, leap day did not occur in the last 365 days.

If the application has to display the return value, it implicitly converts it to text, thereby allowing the display format to change depending on your culture code. See Available Languages and Cultures for a list of the culture codes used by Neurons for ITSM.



If today is April 10, 2014 it returns the DateTime value for April 10, 2013.
