217 weeks ago from today was 26 Sep 2020, a Saturday. Anytime we’re subtracting halves of the year, we need to ensure that we’re still in 2024. It looks like 217 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 1519 days on a calendar until getting my solution of Saturday September 26, 2020.
All of our day calculators are measured and QA'd by our engineer. Read more about the Git process here. But here's how 217 weeks ago gets calculated on each visit:
217 weeks is Saturday September 26, 2020 or could be if you only want workdays. This calculation takes 217 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 September 26, 2020 date.
