    Date.prototype.setMonth()

    Summary

    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

    Example: Using setMonth()

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