humanize-duration
Advanced tools
The humanize-duration npm package is used to convert durations, given in milliseconds, into human-readable strings. It is useful for displaying time durations in a more understandable format for users.
Basic Usage
This feature allows you to convert a duration in milliseconds to a human-readable string. In this example, 3000 milliseconds is converted to '3 seconds'.
const humanizeDuration = require('humanize-duration');
console.log(humanizeDuration(3000)); // '3 seconds'Custom Units
This feature allows you to specify custom units for the duration. In this example, 3600000 milliseconds is converted to '1 hour' using hours and minutes as units.
const humanizeDuration = require('humanize-duration');
console.log(humanizeDuration(3600000, { units: ['h', 'm'] })); // '1 hour'Language Support
This feature allows you to specify the language for the output string. In this example, 3000 milliseconds is converted to '3 segundos' in Spanish.
const humanizeDuration = require('humanize-duration');
console.log(humanizeDuration(3000, { language: 'es' })); // '3 segundos'Round
This feature allows you to round the duration to the nearest unit. In this example, 1234567 milliseconds is rounded to '20 minutes'.
const humanizeDuration = require('humanize-duration');
console.log(humanizeDuration(1234567, { round: true })); // '20 minutes'Largest
This feature allows you to limit the number of units in the output string. In this example, 1234567890 milliseconds is converted to '14 days, 6 hours' with a limit of 2 units.
const humanizeDuration = require('humanize-duration');
console.log(humanizeDuration(1234567890, { largest: 2 })); // '14 days, 6 hours'Moment.js is a comprehensive library for parsing, validating, manipulating, and formatting dates and times in JavaScript. It includes functionality for humanizing durations, but it is more heavyweight compared to humanize-duration.
date-fns is a modern JavaScript date utility library that provides a variety of functions for working with dates, including humanizing durations. It is modular and tree-shakeable, making it a lighter alternative to Moment.js.
Luxon is a modern JavaScript library for working with dates and times, created by one of the Moment.js developers. It offers a more modern API and includes features for humanizing durations, similar to humanize-duration.
I have the time in milliseconds and I want it to become "30 minutes" or "3 days, 1 hour". Enter Humanize Duration!
This library is in maintenance mode. New languages and bug fixes will be added but no new features will be. If you're interested in helping out by taking over the project, please see this GitHub issue.
This package is available as humanize-duration on npm and Bower. You can also include the JavaScript file in the browser.
In the browser:
<script src="humanize-duration.js"></script>
<script>
humanizeDuration(12000)
</script>
In Node (or Browserify or Webpack or anywhere with CommonJS):
var humanizeDuration = require('humanize-duration')
humanizeDuration(12000) // '12 seconds'
By default, Humanize Duration will humanize down to the second, and will return a decimal for the smallest unit. It will humanize in English by default.
humanizeDuration(3000) // '3 seconds'
humanizeDuration(2250) // '2.25 seconds'
humanizeDuration(97320000) // '1 day, 3 hours, 2 minutes'
You can change the settings by passing options as the second argument:
language
Language for unit display (accepts an ISO 639-1 code from one of the supported languages).
humanizeDuration(3000, { language: 'es' }) // '3 segundos'
humanizeDuration(5000, { language: 'ko' }) // '5 초'
delimiter
String to display between the previous unit and the next value.
humanizeDuration(22140000, { delimiter: ' and ' }) // '6 hours and 9 minutes'
humanizeDuration(22140000, { delimiter: '--' }) // '6 hours--9 minutes'
spacer
String to display between each value and unit.
humanizeDuration(260040000, { spacer: ' whole ' }) // '3 whole days, 14 whole minutes'
humanizeDuration(260040000, { spacer: '' }) // '3days, 14minutes'
largest
Number representing the maximum number of units to display for the duration.
humanizeDuration(1000000000000) // '31 years, 8 months, 1 week, 19 hours, 46 minutes, 40 seconds'
humanizeDuration(1000000000000, { largest: 2 }) // '31 years, 8 month'
units
Array of strings to define which units are used to display the duration (if needed). Can be one, or a combination of any, of the following: ['y', 'mo', 'w', 'd', 'h', 'm', 's', 'ms']
humanizeDuration(3600000, { units: ['h'] }) // '1 hour'
humanizeDuration(3600000, { units: ['m'] }) // '60 minutes'
humanizeDuration(3600000, { units: ['d', 'h'] }) // '1 hour'
round
Boolean value. Use true to round the smallest unit displayed (can be combined with largest and units).
humanizeDuration(1200) // '1.2 seconds'
humanizeDuration(1200, { round: true }) // '1 second'
humanizeDuration(1600, { round: true }) // '2 seconds'
decimal
String to substitute for the decimal point in a decimal fraction.
humanizeDuration(1200) // '1.2 seconds'
humanizeDuration(1200, { decimal: ' point ' }) // '1 point 2 seconds'
conjunction
String to include before the final unit. You can also set serialComma to false to eliminate the final comma.
humanizeDuration(22140000, { conjunction: ' and ' }) // '6 hours and 9 minutes'
humanizeDuration(22141000, { conjunction: ' and ' }) // '6 hours, 9 minutes, and 1 second'
humanizeDuration(22140000, { conjunction: ' and ', serialComma: false }) // '6 hours and 9 minutes'
humanizeDuration(22141000, { conjunction: ' and ', serialComma: false }) // '6 hours, 9 minutes and 1 second'
unitMeasures
Customize the value used to calculate each unit of time.
humanizeDuration(400) // '0.4 seconds'
humanizeDuration(400, { // '1 year, 1 month, 5 days'
unitMeasures: {
y: 365,
mo: 30,
w: 7,
d: 1
}
})
Combined example
humanizeDuration(3602000, {
language: 'es',
round: true,
spacer: ' glorioso ',
units: ['m']
}) // '60 glorioso minutos'
If you find yourself setting same options over and over again, you can create a humanizer that changes the defaults, which you can still override later.
var spanishHumanizer = humanizeDuration.humanizer({
language: 'es',
units: ['y', 'mo', 'd']
})
spanishHumanizer(71177400000) // '2 años, 3 meses, 2 días'
spanishHumanizer(71177400000, { units: ['d', 'h'] }) // '823 días, 19.5 horas'
You can also add new languages to humanizers. For example:
var shortEnglishHumanizer = humanizeDuration.humanizer({
language: 'shortEn',
languages: {
shortEn: {
y: function() { return 'y' },
mo: function() { return 'mo' },
w: function() { return 'w' },
d: function() { return 'd' },
h: function() { return 'h' },
m: function() { return 'm' },
s: function() { return 's' },
ms: function() { return 'ms' },
}
}
})
shortEnglishHumanizer(15600000) // '4 h, 20 m'
You can also add languages after initializing:
var humanizer = humanizeDuration.humanizer()
humanizer.languages.shortEn = {
y: function(c) { return c + 'y' },
// ...
Internally, the main humanizeDuration function is just a wrapper around a humanizer.
Humanize Duration supports the following languages:
| Language | Code |
|---|---|
| Arabic | ar |
| Catalan | ca |
| Chinese, simplified | zh_CN |
| Chinese, traditional | zh_TW |
| Czech | cs |
| Danish | da |

| Portuguese | pt |
| Russian | ru |
| Spanish | es |

| Vietnamese | vi |
For a list of supported languages, you can use the getSupportedLanguages function.
humanizeDuration.getSupportedLanguages()
// ['ar', 'ca', 'da', 'de' ...]
This function won't return any new languages you define; it will only return the defaults supported by the library.
