Date.prototype.setUTCHours()

The setUTCHours() method of Date instances changes the hours, minutes, seconds, and/or milliseconds for this date according to universal time.

Try it

Syntax

setUTCHours(hoursValue)
setUTCHours(hoursValue, minutesValue)
setUTCHours(hoursValue, minutesValue, secondsValue)
setUTCHours(hoursValue, minutesValue, secondsValue, msValue)

Parameters

hoursValue: An integer between 0 and 23 representing the hours.
minutesValue Optional: An integer between 0 and 59 representing the minutes.
secondsValue Optional: An integer between 0 and 59 representing the seconds. If you specify secondsValue, you must also specify minutesValue.
msValue Optional: An integer between 0 and 999 representing the milliseconds. If you specify msValue, you must also specify minutesValue and secondsValue.

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 minutesValue, secondsValue, and msValue parameters, the values returned from the getUTCMinutes(), getUTCSeconds(), and getUTCMilliseconds() methods are used.

If a parameter you specify is outside of the expected range, setUTCHours() attempts to update the date information in the Date object accordingly. For example, if you use 100 for secondsValue, the minutes will be incremented by 1 (minutesValue + 1), and 40 will be used for seconds.

Examples

Using setUTCHours()

const theBigDay = new Date();
theBigDay.setUTCHours(8);
