What is setUTCDate() in Javascript?
The setUTCDate function in JavaSript is a method of the Date class which is used to set the value of day following the Universal Time Coordinated (UTC) time.
Parameters
Date.setUTCDate(newDayValue)
The function takes in one parameter that is an integer.
In the above snippet of code, newDayValue is an integer with an expected value between 1 and 31.
If a number greater than 31 or lesser than 0 is passed, the month’s value is adjusted accordingly.
Return value
The total number of milliseconds from 1 January 1970 00:00:00 UTC and the updated date is returned.
Example
In the code below, an unexpected value is passed to the setUTCDate function. Entering a negative number makes a date go back by the specified number of days:
// an object of Date type is created to apply the function onvar obj = new Date('November 1, 2001 09:24:21');// Date is printed in DAY:MONTH:YEAR format in UTCconsole.log("DATE BEFORE FUNCTION CALL: " + obj.getUTCDate() + " : " + obj.getUTCMonth() + " : " + obj.getUTCFullYear())// setUTCDate function is called with an unexpected value.// It'll update the value of the month accordinglyobj.setUTCDate(-10);console.log("DATE AFTER FUNCTION CALL: " + obj.getUTCDate() + " : " + obj.getUTCMonth() + " : " + obj.getUTCFullYear())
