First get the current date and subtract the current date from the starting date of the year. Divide the result with milli seconds in one day
```js
function days (d) {
  return Math.ceil((new Date(d.getTime())-new Date(d.getFullYear(), 0, 1))/86400000);
}
console.log(days(new Date(2020, 4, 15)))
```
