412 weeks ago from today was 01 Jan 2017, a Sunday. Anytime we’re subtracting halves of the year, we need to ensure that we’re still in 2024. It looks like 412 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 2884 days on a calendar until getting my solution of Sunday January 01, 2017.
All of our day calculators are measured and QA'd by our engineer. Read more about the Git process here. But here's how 412 weeks ago gets calculated on each visit:
412 weeks is Sunday January 01, 2017 or could be if you only want workdays. This calculation takes 412 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 January 01, 2017 date.
