1280 weeks ago from today was 20 May 2000, a Saturday. Anytime we’re subtracting halves of the year, we need to ensure that we’re still in 2024. It looks like 1280 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 8960 days on a calendar until getting my solution of Saturday May 20, 2000.
All of our day calculators are measured and QA'd by our engineer. Read more about the Git process here. But here's how 1280 weeks ago gets calculated on each visit:
1280 weeks is Saturday May 20, 2000 or could be if you only want workdays. This calculation takes 1280 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 May 20, 2000 date.
