The date.setUTCFullYear() is an inbuilt function in JavaScript which is used to set year into a date object according to universal time which is created using date() constructor.
Syntax:
DateObj.setUTCFullYear(year_Value);
DateObj is a valid Date object created using Date() constructor in which we want to set the year.
Parameter: Here parameter year_Value is the value of year which is used to set in date() constructor.
Return Values: It returns the new i.e updated year according to universal time which is set by setUTCFullYear() function.
Below program illustrates the setUTCFullYear() function:
// Here a date has been assigned according // to universal time while creating Date object var dateobj = new Date( 'October 13, 1996 05:35:32 GMT-3:00' ); // new year 1992 is being set in above Date // Object with the help of setUTCFullYear() function dateobj.setUTCFullYear(1992); // new year from above Date Object is // being extracted using getUTCFullYear() var B = dateobj.getUTCFullYear(); // Printing new year console.log(B); |
Output:
> 1992
Errors and Exceptions
- Code #1: If in Date() constructor we do not give any year, still setUTCFullYear() function will be able to set new year according to universal time which is given as its parameter.
// Here year according to universal time has not
// been assigned while creating Date object
var
dateobj =
new
Date(
'October 13, 05:35:32 GMT-3:00'
);
// new year 1992 is being set in above Date
// Object with the help of setUTCFullYear() function
dateobj.setUTCFullYear(1992);
// new year from above Date Object is
// being extracted using getUTCFullYear()
var
B = dateobj.getUTCFullYear();
// Printing new year
console.log(B);
Output:
> 1992
- Code #2: If nothing as parameter is given in Date() constructor, still setUTCFullYear() function will be able to set year in the created Date object but month and date remains current ones.
// Here nothing has been assigned
// while creating Date object
var
dateobj =
new
Date();
// new year 2007 is being set in above Date
// Object with the help of setUTCFullYear() function
dateobj.setUTCFullYear(2007);
// Year from above Date Object is
// being extracted using getUTCFullYear()
var
B = dateobj.getUTCFullYear();
// month from above Date Object is
// being extracted using getUTCMonth()
var
C = dateobj.getUTCMonth();
// date from above Date Object is
// being extracted using getUTCDate()
var
D = dateobj.getUTCDate();
// Printing new year
console.log(B);
// Printing current month
console.log(C);
// Printing current date
console.log(D);
Output:
> 2007 > 2 > 30
Here in output 2 is the month of March because month name start from 0 to 11 i.e, 0 for January and 11 for December.
And 30 is the current date.
