Date.prototype.setUTCDate()

The setUTCDate() method changes the day of the month of a given Date instance, based on UTC time.

To instead change the day of the month for a given Date instance based on local time, use the setDate() method.

Try it

Syntax

setUTCDate(dayValue)

Parameters

dayValue: 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 the dayValue is outside of the range of date values for the month, setDate() will update the Date object accordingly.

For example, if 0 is provided for dayValue, the date will be set to the last day of the previous month. If you use 40 for dayValue, and the month stored in the Date object is June, the day will be changed to 10 and the month will be incremented to July.

If a negative number is provided for dayValue, the date will be set counting backwards from the last day of the previous month. -1 would result in the date being set to 1 day before the last day of the previous month.

Examples

Using setUTCDate()

const theBigDay = new Date();
theBigDay.setUTCDate(20);
