moment-business-days-diff

This is a Moment.js plugin that allows you to work with only business days (Monday to Friday). You can customize the working week

Usage

// NodeJS: require instead of standard moment package
const moment = require('moment-business-days');
// You'll be able use Moment.js as you normally do

<!-- Browser -->
<!-- NB: add after moment.js -->
<script src="moment.js"></script>
<script src="moment-business-days-diff.js"></script>

Use localization to configure business days

const moment = require('moment-business-days');
 
moment.updateLocale('us', {
   workingWeekdays: [1, 2, 3, 4, 5, 6]
});
 
// Defines days from 1 (Monday) to 6 (Saturday) as business days.
// When omitting this configuration parameter, business days are based on locale default
