603 weeks ago from today was 30 Jul 2013, a Tuesday. Anytime we’re subtracting halves of the year, we need to ensure that we’re still in 2025. It looks like 603 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 4221 days on a calendar until getting my solution of Tuesday July 30, 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 603 weeks ago gets calculated on each visit:
603 weeks is Tuesday July 30, 2013 or could be if you only want workdays. This calculation takes 603 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 July 30, 2013 date.
