869 weeks ago from today was 19 Jul 2008, a Saturday. Anytime we’re subtracting halves of the year, we need to ensure that we’re still in 2025. It looks like 869 weeks from now will bring us back to pre 2024 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 6083 days on a calendar until getting my solution of Saturday July 19, 2008.
All of our day calculators are measured and QA'd by our engineer. Read more about the Git process here. But here's how 869 weeks ago gets calculated on each visit:
869 weeks is Saturday July 19, 2008 or could be if you only want workdays. This calculation takes 869 weeks and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Saturday July 19, 2008 date.
