819 weeks ago from today was 18 Mar 2009, a Wednesday. Anytime we’re subtracting halves of the year, we need to ensure that we’re still in 2024. It looks like 819 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 5733 days on a calendar until getting my solution of Wednesday March 18, 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 819 weeks ago gets calculated on each visit:
819 weeks is Wednesday March 18, 2009 or could be if you only want workdays. This calculation takes 819 weeks and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Wednesday March 18, 2009 date.
