dateObj.setMonth()

The setMonth() method sets the month for a specified date according to the currently set year.

Syntax

dateObj.setMonth(monthValue[, dayValue])

Versions prior to JavaScript 1.3

dateObj.setMonth(monthValue)

Parameter

monthValue: An integer between 0 and 11, representing the months January through December.
dayValue: Optional. An integer from 1 to 31, representing the day of the month.

Description

If you do not specify the dayValue parameter, the value returned from the getDate() method is used.

If a parameter you specify is outside of the expected range, setMonth() attempts to update the date information in the Date object accordingly. For example, if you use 15 for monthValue, the year will be incremented by 1, and 3 will be used for month.

Examples

Using `setMonth()`

var theBigDay = new Date();
theBigDay.setMonth(6);
