1 millisecond before that, to be precise nextMon is now set to the ending of the current month For this, you can use the endOf function: const today = moment() Suppose, you need to get the timestamp of the beginning of the next month (or next year). For example, you can add or subtract: const past = moment().subtract(2, 'month') // To pastĬonst future = moment().add(1, 'year') // Back to futureįor the second argument, you can provide any of the following: Surely, there are easier ways to manipulate time for different use cases. For example, here is how you can change values directly: const jesusBday = moment() It can also manipulate time in many ways with an easy interface. Manipulate timeįormatting time is not the only strength of MomenJS. Similarly, there is a function toNow() which does the opposite. For example, if you need to display a last seen status, you can use the fromNow function: const almostNow = moment().subtract(15, 'minutes') Ĭonst yesterday = moment().subtract(1, 'day').Ĭonst monthAgo = moment().subtract(1, 'month') Ĭonsole.log(omNow()) // 15 minutes agoĬonsole.log(omNow()) // a day agoĬonsole.log(omNow()) // a month ago Hour in 24h format with and without trailing zerosĪdditionally, there are a couple of handy functions that can make formatting even easier. Hour in 12h format with and without trailing zeros Here is a list of common formatting tokens you can use in format(): M Moment().format("dddd, MMMM Do YYYY, h:mm:ss a") The only function you need is format, which accepts a string as a template. Moment provides a simple interface for formatting time. If you want to create a moment object using current date and time, just call moment() without any arguments. If you are creating timestamps using built-in new Date(), you can also use it to create moment objects: const timestamp = new Date() If you are getting the timestamp from server, it has to be an ISO-compliant date string, or a Unix timestamp in milliseconds: const timestamp = await getTimeFromServer() Ĭonst momentTimestamp = moment(timestamp) Ĭonsole.log(momentTimestamp.format()) // T08:02:17-05:00 To output time in a human-readable format, you first have to convert it to moment object. If you are including the script in HTML, the moment object will be available globally, so you do not have to import it. Then, it would be available to import like this: const moment = require('momentjs') If you are not using a package manager, you can just include the script directly in HTML: You can install it using your package manager of choice: npm i -S momentjs It has a very easy and straightforward API and is pretty much an industry standard for date-related tasks in JavaScript applications. It lets you create timestamps, modify them (add, subtract, etc), query them (is one before another), and display them in a variety of human-readable formats. MomentJS is an all-in-one solution for date time processing in your JavaScript app.
