date.setUTCMonth

The setUTCMonth() method sets the month for a specified date according to universal time.

Syntax

dateObj.setUTCMonth(monthValue[, dayValue])

Parameters

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.

Return value

The number of milliseconds between 1 January 1970 00:00:00 UTC and the updated date.

Description

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

If a parameter you specify is outside of the expected range, setUTCMonth() 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 setUTCMonth()

var theBigDay = new Date();
theBigDay.setUTCMonth(11);
