609 weeks ago from today was 13 Jul 2013, a Saturday. Anytime we’re subtracting halves of the year, we need to ensure that we’re still in 2025. It looks like 609 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 4263 days on a calendar until getting my solution of Saturday July 13, 2013.
All of our day calculators are measured and QA'd by our engineer. Read more about the Git process here. But here's how 609 weeks ago gets calculated on each visit:
609 weeks is Saturday July 13, 2013 or could be if you only want workdays. This calculation takes 609 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 July 13, 2013 date.
