All of our day calculators are measured and QA'd by our engineer. Read more about the Git process here. But here's how 1899 days ago gets calculated on each visit:
1899 days is Sunday September 01, 2019 or could be if you only want workdays. This calculation takes 1899 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 September 01, 2019 date.
