 | 
						|
A lightweight JavaScript date library for parsing, validating, manipulating, and formatting dates.

## Port to ECMAScript 6 (version 2.10.0)
 | 
						|
 | 
						|
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.
 | 
						|
 | 
						|
## Upgrading to 2.0.0
 | 
						|
 | 
						|
There are a number of small backwards incompatible changes with version 2.0.0. [See the full descriptions here](https://gist.github.com/timrwood/e72f2eef320ed9e37c51#backwards-incompatible-changes)
 | 
						|
 | 
						|
 * 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.
