$addyears

Calculates a date value by adding years to (or subtracting years from) a specified date value.

Syntax

$addyears(date,number)

Parameters

Return Value

Number, representing a DATE value.

Comments

Use $addyears to perform arithmetic with date values. The $addyears function calculates a date value by adding a number representing years to a date value. If number is negative, the effect is to subtract the years from the date.

The + (add) and – (subtract) operators can be used to achieve the same results.

If date or the result of the $addyears expression is an invalid date (e.g., 19930231), it is adjusted to produce a valid date (e.g., 19930228).

Example

If $Date has the value 19981225, then

$addyears($date,5)

Evaluates to 20041225.

$addyears($date,-5)

Evaluates to 19931225.

$addyears(19980229,1)

Evaluates to 19990228.
