215 weeks ago from today was 10 Oct 2020, a Saturday. Anytime we’re subtracting halves of the year, we need to ensure that we’re still in 2024. It looks like 215 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 1505 days on a calendar until getting my solution of Saturday October 10, 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 215 weeks ago gets calculated on each visit:
215 weeks is Saturday October 10, 2020 or could be if you only want workdays. This calculation takes 215 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 October 10, 2020 date.
