JavaScript | Adding minutes to Date object
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.
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.
- 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)
