291 weeks ago from today was 07 Oct 2018, a Sunday. Anytime we’re subtracting halves of the year, we need to ensure that we’re still in 2024. It looks like 291 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 2037 days on a calendar until getting my solution of Sunday October 07, 2018.
All of our day calculators are measured and QA'd by our engineer. Read more about the Git process here. But here's how 291 weeks ago gets calculated on each visit:
291 weeks is Sunday October 07, 2018 or could be if you only want workdays. This calculation takes 291 weeks and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Sunday October 07, 2018 date.
