Moment.js moment().quarter() Method

The moment().quarter() method is used to get or set the quarter of the Moment object. There are 4 quarters in a year, hence this method accepts a value from 1 to 4. A value outside of the range will bubble up the year of the Moment to the next or previous years.

Note: The day of Moment would stay the same when this method is used for setting the quarter.

Syntax:

moment().quarter( Number );

Parameters: This method accepts a single parameter as mentioned above and described below:

• Number: It is the quarter that has to be set for the Moment object. it is an optional parameter.

Return Value: This method returns the current quarter of the Moment.

Note: This will not work in the normal Node.js program because it requires an external moment.js library to be installed globally or in the project directory.

Moment.js can be installed using the following command:

Installation of moment module:

npm install moment
