Journey

I have been doing this every day since September 1st, 2018
On Sep 17th, 2019, day 381, I joined eBay
On May 27th, 2021, day 1000
On June 1st, 2021, day 1004, I joined Facebook

const start = new Date("09/01/2018"); const now = new Date(); console.log(Math.ceil((now - start) / (1000 * 3600 * 24)));
