180 weeks ago from today was 13 Feb 2021, a Saturday. Anytime we’re subtracting halves of the year, we need to ensure that we’re still in 2024. It looks like 180 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 1260 days on a calendar until getting my solution of Saturday February 13, 2021.
All of our day calculators are measured and QA'd by our engineer. Read more about the Git process here. But here's how 180 weeks ago gets calculated on each visit:
180 weeks is Saturday February 13, 2021 or could be if you only want workdays. This calculation takes 180 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 February 13, 2021 date.
