All of our day calculators are measured and QA'd by our engineer. Read more about the Git process here. But here's how 2580 days ago gets calculated on each visit:
2580 days is Thursday October 26, 2017 or could be if you only want workdays. This calculation takes 2580 days and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Thursday October 26, 2017 date.
