All of our day calculators are measured and QA'd by our engineer. Read more about the Git process here. But here's how 1583 days ago gets calculated on each visit:
1583 days is Sunday May 24, 2020 or could be if you only want workdays. This calculation takes 1583 days and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Sunday May 24, 2020 date.
