Question

Is there a natural language parser for date/times in javascript?

Answer 1

I made Chrono a small library for parsing dates in JavaScript. I added a date range parsing feature (such as '12 Nov - 13 Dec 2012') .

Answer 2

SugarJS supports some natural language parsing of dates and times.

You can jump to the live example here: http://sugarjs.com/dates

For example, it supports the following inputs:

• the day after tomorrow
• 2 weeks from monday
• May 25th of next year

You can then covert the result into different date formats or use the API to further manipulate the date.

Answer 3

Does Date.js satisfy your needs? Or are you looking for something else?

Answer 4

Chrono v2 is the only library I've found that also parses timezones.

Unfortunately, the only documented way of using it is via NPM (npm i chrono-node) or as ES6 Module (import * as chrono from 'chrono-node'), but I found a way to use the library with the traditional script tag approach for those interested.

Non-NPM / non-module usage:

1. Include this script: https://www.unpkg.com/chrono-node/dist/bundle.js
2. Use the global variable chrono in your script _{(available methods here)}

E.g. chrono.parseDate('Tomorrow at 4 PM PST')

⚠ Note: I have not tested this extensively, so don't expect it to work flawlessly

Answer 5

For node, I've found chrono to work well

Chrono supports most date and time formats, such as :

• Today, Tomorrow, Yesterday, Last Friday, etc
• 17 August 2013 - 19 August 2013
• This Friday from 13:00 - 16.00
• 5 days ago
• 2 weeks from now
• Sat Aug 17 2013 18:40:39 GMT+0900 (JST)
• 2014-11-30T08:15:30-05:30

Answer 6

Sherlock is a great one.

var Sherlock = require('sherlockjs');
var sherlocked = Sherlock.parse('Homework 5 due next monday at 3pm');

// Basic properties
var title = sherlocked.eventTitle;    // 'Homework 5 due'
var startDate = sherlocked.startDate; // Date object pointing to next monday at 3pm
var endDate = sherlocked.endDate;     // null in this case, since no duration was given
var isAllDay = sherlocked.isAllDay;   // false, since a time is included with the event

// Example of an additional custom property added by Watson
var validated = sherlocked.validated; // true

Answer 7

You can use the jQuery datepicker translation, get the day and month number and select the day from datepicker days.

You can add values to this object, and you can download up to 60 languages I think. (The object below is not complete, I removed some code to simplify it).

$.datepicker.regional['sv'] = { 
  monthNames:['Januari','Februari','Mars','April','Maj','Juni','Juli','Augusti','September','Oktober','November','December'],
  monthNamesShort: ['Jan','Feb','Mar','Apr','Maj','Jun','Jul','Aug','Sep','Okt','Nov','Dec'],
  dayNamesShort: ['Sön','Mån','Tis','Ons','Tor','Fre','Lör'],
  dayNames: ['Söndag','Måndag','Tisdag','Onsdag','Torsdag','Fredag','Lördag'],
  dayNamesMin: ['Sö','Må','Ti','On','To','Fr','Lö']
};

Now get the day and month number

var dateObject = new Date();
var day = dateObject.getDay();
var month = dateObject.getMonth();
var monthText = $.datepicker.regional['sv']['monthNames'][month];
var dayText = $.datepicker.regional['sv']['dayNames'][day];
