Here is a solution similar to other answers but with a different approach, I started from years instead of millis, I think is more accurate this way.

    const date = new Date(startDate).getTime()
    const today = new Date().getTime()
    
    // 1000 millis => sec , 86400 sec => day , 365 day => year
    let years = (today - date) / (1000 * 86400 * 365)
    let months = (years - Math.floor(years)) * 12
    let days = (months - Math.floor(months)) * 30
    let hours = (days - Math.floor(days)) * 24
    let minutes = (hours - Math.floor(hours)) * 60
    let sec = (minutes - Math.floor(minutes)) * 60
    let milli = (sec - Math.floor(sec)) * 1000
    
    years = Math.floor(years)
    months = Math.floor(months)
    days = Math.floor(days)
    hours = Math.floor(hours)
    minutes = Math.floor(minutes)
    sec = Math.floor(sec)
    milli = Math.floor(milli)

Without having a calendar and knowing the input dates, the best you can do is be approximate.

Here is a script that shows the time elapsed since midnight last night.

var diff = Date.now() - Date.parse("July 13, 2016");

var seconds = Math.floor(diff / 1000),
    minutes = Math.floor(seconds / 60),
    hours   = Math.floor(minutes / 60),
    days    = Math.floor(hours / 24),
    months  = Math.floor(days / 30),
    years   = Math.floor(days / 365);

seconds %= 60;
minutes %= 60;
hours %= 24;
days %= 30;
months %= 12;

console.log("Years:", years);
console.log("Months:", months);
console.log("Days:", days);
console.log("Hours:", hours);
console.log("Minutes:", minutes);
console.log("Seconds:", seconds);

There is no inbuilt method to convert given millisecond to equivalent seconds, minutes, hours, days, months or years.

You will have to use math. Although you will only be able to convert accurately up to days. Months and years will vary as months are either 28, 29, 30 or 31 and there are leap years.

Consider having a look at http://momentjs.com/ before you write anything on your own, as you can do a lot more with this library like adding and subtracting days or hours etc
