681 weeks ago from today was 11 Nov 2011, a Friday. Anytime we’re subtracting halves of the year, we need to ensure that we’re still in 2024. It looks like 681 weeks from now will bring us back to pre 2023 and we’ll need to factor this into our subtraction because it will change the calendar and fiscal years. For larger calculations like this, I start by subtracting total days, then counting backwards 4767 days on a calendar until getting my solution of Friday November 11, 2011.
All of our day calculators are measured and QA'd by our engineer. Read more about the Git process here. But here's how 681 weeks ago gets calculated on each visit:
681 weeks is Friday November 11, 2011 or could be if you only want workdays. This calculation takes 681 weeks and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Friday November 11, 2011 date.
