Date.prototype.setUTCHours()
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
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 specifyminutesValue
. msValue
Optional-
An integer between 0 and 999 representing the milliseconds. If you specify
msValue
, you must also specifyminutesValue
andsecondsValue
.
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);
