This is a plugin for the dayjs.js and inspired from moment-date-range-plugin In the example below the difference between the 2 dates is 1 month, 2 days, 3 hours, 4 minutes and 5 seconds exactly, however this is simplified to just 'a month' by the library.
var dayjs = require('dayjs');
var relativeTime = require('dayjs/plugin/relativeTime')
dayjs.extend(relativeTime)
var m1 = dayjs('2014-01-01 12:00:00');
var m2 = dayjs('2014-02-03 15:04:05');
var diff = m1().from(m2,true) // 'a month'
Using the plugin, we can display the exact difference using the same 2 dates:
var dayjs = require('dayjs');
var preciseDiff = require('dayjs-precise-range');
//or
//var preciseDiff = require('dayjs/plugin/preciseDiff')
dayjs.extend(preciseDiff);
var m1 = dayjs('2014-01-01 12:00:00');
var m2 = dayjs('2014-02-03 15:04:05');
var diff = dayjs.preciseDiff(m1, m2); // '1 month 2 days 3 hours 4 minutes 5 seconds'
To obtain the numeric values rather than a string, pass the value true as the third argument to the method:
var diff = moment.preciseDiff(m1, m2, true); // {years : 0, months : 1, days : 2, hours : 3, minutes : 4, seconds : 5}
To use the plugin in a web page, add a <script> tag referencing the moment-precise-range.js file, ensuring that the tag appears
after the tag used to include the moment.js library:
<script src="/scripts/days.js"></script>
<script src="/scripts/days-precise-range.js"></script>
To use the plugin within a node.js application, add the following require statement into your code:
require('days-precise-range-plugin');
