The moment npm package is a JavaScript library for parsing, validating, manipulating, and formatting dates. It is widely used for handling dates and times in Node.js and browser applications.
Parsing
Parse a date string into a moment object.
moment('2023-04-05')Validation
Check if a date is valid.
moment('2023-04-05').isValid()Manipulation
Manipulate dates by adding time to the current date.
moment().add(7, 'days')Formatting
Format a moment date object into a string in a specified format.
moment().format('YYYY-MM-DD')Query
Query dates to compare them.
moment().isBefore('2023-12-25')Provides a collection of simple, pure functions for manipulating JavaScript dates. It is modular, allowing you to pick and choose which functions you need, and is generally considered to be a lighter-weight alternative to moment.
Created by one of the original Moment.js team members, Luxon is a modern library for working with dates and times. It offers a fluent API and aims to have a smaller footprint than moment.
Day.js is a minimalist JavaScript library that parses, validates, manipulates, and displays dates and times for modern browsers with a largely Moment.js-compatible API. It is lightweight and its API is designed to be familiar to Moment.js users.
A lightweight JavaScript date library for parsing, validating, manipulating, and formatting dates.
Moment 2.10.0 does not bring any new features, but the code is now written in
ECMAScript 6 modules and placed inside src/. Previously moment.js, locale/*.js and
test/moment/*.js, test/locale/*.js contained the source of the project. Now
the source is in src/, temporary build (ECMAScript 5) files are placed under
build/umd/ (for running tests during development), and the moment.js and
locale/*.js files are updated only on release.
If you want to use a particular revision of the code, make sure to run
grunt transpile update-index, so moment.js and locales/*.js are synced
with src/*. We might place that in a commit hook in the future.
There are a number of small backwards incompatible changes with version 2.0.0. See the full descriptions here
Changed language ordinal method to return the number + ordinal instead of just the ordinal.
Changed two digit year parsing cutoff to match strptime.
Removed moment#sod and moment#eod in favor of moment#startOf and moment#endOf.
Removed moment.humanizeDuration() in favor of moment.duration().humanize().
Removed the lang data objects from the top level namespace.
Duplicate Date passed to moment() instead of referencing it.
We're looking for co-maintainers! If you want to become a master of time please write to ichernev.
Moment.js is freely distributable under the terms of the MIT license.
