The date.setMinutes() is an inbuilt function in JavaScript which is used to set minutes into a Date object which is created using Date() constructor.
Syntax:
DateObj.setMinutes(Minutes_Value)
DateObj is a valid Date object created using Date() constructor in which we want to set the minute. Value of minute is from 0 to 59.
Parameter: Here parameter minutes_Value is the value of minutes which is used to set in Date() constructor.
Return Value: It returns the new date with updated minute which is set by setMinutes() function.
Below program illustrate the setMinutes() function:
// Here a date has been assigned // while creating Date object var dateobj = new Date( 'October 13, 1996 05:35:32' ); // new minute of 52 is being set in above Date // Object with the help of setMinutes() function dateobj.setMinutes(52); // new minute from above Date Object is // being extracted using getMinutes() var B = dateobj.getMinutes(); // Printing new minute console.log(B); |
Output:
52
Errors and Exceptions
- Code #1: If in Date() constructor we do not give any minute while creating the Date object, still setMinutes() function set new minute which is given as its parameter.
// Here minute has not been assigned
// while creating Date object
var
dateobj =
new
Date(
'October 13, 1996'
);
// new minute of 51 is being set in above Date
// Object with the help of setMinutes() function
dateobj.setMinutes(51);
// new minute from above Date Object is
// being extracted using getMinutes()
var
B = dateobj.getMinutes();
// Printing new minute
console.log(B);
Output:
51
- Code #2: If nothing as parameter is given in Date() constructor, still setMinutes() function set minute but month, year, date etc become current ones.
// Here nothing has been assigned
// while creating Date object
var
dateobj =
new
Date();
// new minute of 42 is being set in above Date
// Object with the help of setMinutes() function
dateobj.setMinutes(42);
// Minutes from above Date Object is
// being extracted using getMinutes()
var
B = dateobj.getMinutes();
// month from above Date Object is
// being extracted using getMonth()
var
C = dateobj.getMonth();
// date from above Date Object is
// being extracted using getDate()
var
D = dateobj.getDate();
// year from above Date Object is
// being extracted using getFullYear()
var
E = dateobj.getFullYear();
// Printing new minutes
console.log(B);
// Printing current month
console.log(C);
// Printing current date
console.log(D);
// Printing current year
console.log(E);
Output:
42 3 1 2018
Here 42 is the new minutes, 3 is the current month i.e April, 1 is the current date and 2018 is the current year.
- Code #3: If value of minute is 66 as given in the parameter of setMinutes() function, It will set 6 as the minute because minute range is form 0 to 59 and (66%60 = 6).
// Here date has been assigned
// while creating Date object
var
dateobj =
new
Date(
'October 13, 1996 05:35:32'
);
// new minute of 66 is being set in above Date
// Object with the help of setMinutes() function
dateobj.setMinutes(66);
// minute from above Date Object is
// being extracted using getMinutes()
var
B = dateobj.getMinutes();
// Hour from above Date Object is
// being extracted using getHours()
var
C = dateobj.getHours();
// Printing new minute
console.log(B);
// Printing hour
console.log(C);
Output:
6 6
Here 6 is the new minute and hour becomes 06 from 05 because minute range is form 0 to 59 i.e, total 60 and we set new minute as 66 which increase hour by one to 06 from 05 and minute becomes 6.
