All of our day calculators are measured and QA'd by our engineer. Read more about the Git process here. But here's how 1664 days ago gets calculated on each visit:
1664 days is Wednesday March 04, 2020 or could be if you only want workdays. This calculation takes 1664 days and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Wednesday March 04, 2020 date.
