How to get difference between 2 Dates in Years, Months and days using moment.js?
For example the difference between 4/5/2014 & 2/22/2013 should be calculated as 1 Year, 1 Month and 14 Days.
Moment.js can't handle this scenario directly. It does allow you to take the difference between two moments, but the result is an elapsed duration of time in milliseconds. Moment does have a Duration object, but it defines a month as a fixed unit of 30 days - which we know is not always the case.
Fortunately, there is a plugin already created for moment called "Precise Range", which does the right thing. Looking at the source, it does something similar to torazaburo's answer - but it properly accounts for the number of days in the month to adjust.
After including both moment.js and this plugin (readable-range.js) in your project, you can simply call it like this:
var m1 = moment('2/22/2013','M/D/YYYY'); var m2 = moment('4/5/2014','M/D/YYYY'); var diff = moment.preciseDiff(m1, m2); console.log(diff);
The output is "1 year 1 month 14 days"
