All of our day calculators are measured and QA'd by our engineer. Read more about the Git process here. But here's how 1641 days ago gets calculated on each visit:
1641 days is Sunday May 17, 2020 or could be if you only want workdays. This calculation takes 1641 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 17, 2020 date.
