Date.prototype.setUTCMonth()

The setUTCMonth() method of Date instances changes the month and/or day of the month for this date according to universal time.

Try it

Syntax

setUTCMonth(monthValue)
setUTCMonth(monthValue, dateValue)

Parameters

monthValue: An integer representing the month: 0 for January, 1 for February, and so on.
dateValue Optional: An integer from 1 to 31 representing the day of the month.

Return value

Changes the Date object in place, and returns its new timestamp. If a parameter is NaN (or other values that get coerced to NaN, such as undefined), the date is set to Invalid Date and NaN is returned.

Description

If you do not specify the dateValue 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()

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