All of our day calculators are measured and QA'd by our engineer. Read more about the Git process here. But here's how 2591 days ago gets calculated on each visit:
2591 days is Sunday October 15, 2017 or could be if you only want workdays. This calculation takes 2591 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 October 15, 2017 date.
