402 weeks ago from today was 20 Aug 2016, a Saturday. Anytime we’re subtracting halves of the year, we need to ensure that we’re still in 2024. It looks like 402 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 2814 days on a calendar until getting my solution of Saturday August 20, 2016.
All of our day calculators are measured and QA'd by our engineer. Read more about the Git process here. But here's how 402 weeks ago gets calculated on each visit:
402 weeks is Saturday August 20, 2016 or could be if you only want workdays. This calculation takes 402 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 August 20, 2016 date.
