838 weeks ago from today was 27 Jan 2009, a Tuesday. Anytime we’re subtracting halves of the year, we need to ensure that we’re still in 2025. It looks like 838 weeks from now will bring us back to pre 2024 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 5866 days on a calendar until getting my solution of Tuesday January 27, 2009.
All of our day calculators are measured and QA'd by our engineer. Read more about the Git process here. But here's how 838 weeks ago gets calculated on each visit:
838 weeks is Tuesday January 27, 2009 or could be if you only want workdays. This calculation takes 838 weeks and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Tuesday January 27, 2009 date.
