MomentJS - Difference

This method gives the difference in milliseconds.

Syntax

moment().diff(Moment|String|Number|Date|Array);
moment().diff(Moment|String|Number|Date|Array, String);
moment().diff(Moment|String|Number|Date|Array, String, Boolean);

This method allows to get the difference in measurements, that is in years, months etc.,

The supported measurements are years, months, weeks, days, hours, minutes, and seconds.

Observe the following examples for a better understanding −

Example 1

var a = moment([2000, 2, 15]);
var b = moment([2007, 8, 16]);
var c = a.diff(b);

Or

Example

var a = moment([2000, 2, 15]).diff(moment([2007, 8, 16]));

Output

Example 2

Here is another example with measurements passed −

var a = moment([2010, 2, 15]).diff(moment([2007, 8, 16]), "years");

Output

Example 3

In case you want the difference with the floating point number, pass true as the third parameter to difference as shown in the code here −

var a = moment([2010, 2, 15]).diff(moment([2007, 8, 16]), "years", true);

Output
