Elegant method to generate array of random dates within two dates

Using Moment.js && @Demven Weir's answer to get a string value like "03/02/1975".

moment(new Date(+(new Date()) - Math.floor(Math.random()*10000000000)))
.format('MM/DD/YYYY');

NOTE: Keep adding a zero at a time to increase the span of years produced.

console.log(
  new Date(new Date() - Math.random()*(1e+12))
)

You can convert the boundary dates to integers (Date.getTime()) and then use Math.random() to generate your random dates within given boundaries. Then go back to Date objects with Date.setTime().

Maybe I am missing something, but isn't this it?

function randomDate(start, end) {
  return new Date(start.getTime() + Math.random() * (end.getTime() - start.getTime()));
}

const d = randomDate(new Date(2012, 0, 1), new Date());
console.log(d);
