Weekdays : 'dimanche_lundi_mardi_mercredi_jeudi_vendredi_samedi'. Months : 'janvier_février_mars_avril_mai_juin_juillet_août_septembre_octobre_novembre_décembre'. The following abridged example, taken from the Moment.js docs, shows how support can be added for French. If you want to support any other language, then assign the key values of that particular language to moment.locale. By default, it supports the English language. It allows you to assign a global language or set the language for a particular moment object. format ( 'dddd Do MMMM, YYYY' ) ) // Thursday 16th January, 2020 const today = moment ( ) const nextWeek = today. If you want a human-readable date, you’ll need to format it accordingly. Note that each of the above examples will return the moment object. subtract ( 7, 'years' ) // subtracts 7 years to current date subtract ( 7, 'months' ) // subtracts 7 months to current date moment ( ). subtract ( 7, 'days' ) // subtracts 7 days to current date moment ( ). Similarly, the subtract() method is shown below.

add ( 7, 'years' ) // adds 7 years to current date

add ( 7, 'months' ) // adds 7 months to current date moment ( ). add ( 7, 'days' ) // adds 7 days to current date moment ( ). The following example shows how seven days, months, or weeks are added to the current date. This is achieved via the add() and subtract() methods. For example, you can add or subtract days, months, years, etc. There are a number of options for manipulating the moment object.

To avoid this, you can put Moment into strict parsing mode by passing it true as a third argument. isValid ( ) ) // Returns true because 2019 matches YYYY log ( moment ( "2019 was a great year because I got married", "YYYY-MM-DD" ). isValid ( ) ) // falseīe aware, however, that Moment gives you the possibility to work with partial dates, which might lead to unexpected results. log ( moment ( "not-a-date", "YYYY-MM-DD" ). This will return true if the date is valid, and false otherwise. In order to perform validation, simply pass a date string to the moment object, along with the desired date format, and call the isValid() method. format ( ) ) Īnother annoying task that Moment.js has greatly simplified is date validation. Moment.js // You have a 'moment' global here const today = moment ( ) console. Moment.js creates a global moment object which can be used to access all the date and time parsing and manipulation functionality.
