23 May, 2019
Given a date and the task is to add minutes to it. To add minutes to the date object in javascript, some methods are used which are listed below:
JavaScript getMinutes() Method: This method returns the Minutes (from 0 to 59) of the provided date and time.Syntax:Date.getMinutes()
Return value: It returns a number, from 0 to 59, representing the minutes.
Syntax:
Date.getMinutes()

Return value: It returns a number, from 0 to 59, representing the minutes.
JavaScript setMinutes() Method: This method set the minutes of a date object. This method can also be used to set the seconds and milliseconds.Syntax:Date.setMinutes(min, sec, millisec)
Parameters:min: It is required parameter. It specifies the integer representing the minutes. Values expected are 0-59, but other values are allowed.sec: It is optional parameter. It specifies the integer representing the seconds. Values expected are 0-59, but other values are allowed.millisec: It is optional parameter. It specifies the integer representing the milliseconds. Values expected are 0-999, but other values are allowed.Note: All the previous three parameters accept values apart from their range and these values adjust like:min = -1, it means the last minute of the previous hour and same for the other parameters.If min value passed to 60, it means the first minute of the next hour and same for the other parameters.Return value: It returns a number, denoting the number of milliseconds between the date object and midnight January 1 1970.
JavaScript setMinutes() Method: This method set the minutes of a date object. This method can also be used to set the seconds and milliseconds.
Syntax:
Date.setMinutes(min, sec, millisec)

Parameters:
min: It is required parameter. It specifies the integer representing the minutes. Values expected are 0-59, but other values are allowed.
sec: It is optional parameter. It specifies the integer representing the seconds. Values expected are 0-59, but other values are allowed.
millisec: It is optional parameter. It specifies the integer representing the milliseconds. Values expected are 0-999, but other values are allowed.
Note: All the previous three parameters accept values apart from their range and these values adjust like:
min = -1, it means the last minute of the previous hour and same for the other parameters.
If min value passed to 60, it means the first minute of the next hour and same for the other parameters.
Return value: It returns a number, denoting the number of milliseconds between the date object and midnight January 1 1970.
JavaScript getTime() method: This method returns the number of milliseconds between midnight of January 1, 1970, and the specified date.Syntax:Date.getTime()
Return value: It returns a number, representing the number of milliseconds since midnight January 1, 1970.
Syntax:
Date.getTime()

Return value: It returns a number, representing the number of milliseconds since midnight January 1, 1970.
JavaScript setTime() method: This method set the date and time by adding/subtracting a defined number of milliseconds to/from midnight January 1, 1970.Syntax:Date.setTime(millisec)
Parameters: It contains single parameter millisec which is required. It specifies the number of milliseconds to be added/subtracted, midnight January 1, 1970.Return value: It returns, representing the number of milliseconds between the date object and midnight January 1 1970.Example 1: This example added 4 minutes to the var today by using setTime() and getTime() method.<!DOCTYPE HTML>  <html>      <head>         <title>             JavaScript | Adding Minutes to  Date object.        </title>    </head>           <body style = "text-align:center;" id = "body">                    <h1 style = "color:green;" >              GeeksForGeeks          </h1>                  <p id = "GFG_UP" style = "font-size:15px; font-weight:bold;">        </p>                  <button onclick = "gfg_Run()">             addMinutes        </button>                  <p id = "GFG_DOWN" style =             "color:green; font-size: 20px; font-weight: bold;">        </p>                  <script>            var el_up = document.getElementById("GFG_UP");            var el_down = document.getElementById("GFG_DOWN");            var today = new Date();            el_up.innerHTML = "Date = " + today;                          Date.prototype.addMins = function(m) {                   this.setTime(this.getTime() + (m*60*1000));                return this;               }                          function gfg_Run() {                var a = new Date();                a.addMins(4);                el_down.innerHTML = a;            }                 </script>     </body>  </html>Output:Before clicking on the button:After clicking on the button:Example 2: This example adds 6 minutes to the var today by using setMinutes() and getMinutes() method.<!DOCTYPE HTML> <html>     <head>         <title>             JavaScript | Adding Minutes to Date object.        </title>    </head>       <body style = "text-align:center;" id = "body">           <h1 style = "color:green;" >             GeeksForGeeks         </h1>          <p id = "GFG_UP" style = "font-size: 15px; font-weight: bold;">        </p>          <button onclick = "gfg_Run()">             addMinutes        </button>          <p id = "GFG_DOWN" style =            "color:green; font-size: 20px; font-weight: bold;">        </p>                  <script>            var el_up = document.getElementById("GFG_UP");            var el_down = document.getElementById("GFG_DOWN");            var today = new Date();            el_up.innerHTML = "Date = " + today;                          Date.prototype.addMinutes= function(m) {                this.setMinutes(this.getMinutes() + m);                return this;            }                          function gfg_Run() {                var a = new Date();                a.addMinutes(6);                el_down.innerHTML = a;            }        </script>     </body> </html>                    Output:Before clicking on the button:After clicking on the button:My Personal Notes
