120 weeks ago from today was 13 Feb 2022, a Sunday. Anytime we’re subtracting halves of the year, we need to ensure that we’re still in 2024. It looks like 120 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 840 days on a calendar until getting my solution of Sunday February 13, 2022.
All of our day calculators are measured and QA'd by our engineer. Read more about the Git process here. But here's how 120 weeks ago gets calculated on each visit:
120 weeks is Sunday February 13, 2022 or could be if you only want workdays. This calculation takes 120 weeks and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Sunday February 13, 2022 date.
