Introduced in DataWeave version 2.4.0.

Parameters

Name Description

nYears

A whole number for the number of years. A positive or negative number is valid.

Example

This example shows how years behaves with different inputs. It adds a year to a DateTime value, and it converts the whole number 4 into a number of years in the Period format (P4Y). Notice that years(-1) + years(2) returns the number of months.
