All of our day calculators are measured and QA'd by our engineer. Read more about the Git process here. But here's how 1880 days ago gets calculated on each visit:
1880 days is Sunday September 22, 2019 or could be if you only want workdays. This calculation takes 1880 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 22, 2019 date.
