40 days ago from today was 20 Mar 2025, a Thursday. As we approach calculations over month in the past, the 30 days in April play significant roles, alongside the day of the week. Since today is Tuesday and still part of the beginning of the week we won't need to add additional days into next week. Counting backwards from today skips several weekends, meaning that subtracting 40 days takes us from the end of of April to potentially crossing far beyond April or March. For those of us focusing on workdays, subtracting 40 days ago necessitates adjustments for the fiscal calendar (don’t worry, I've accounted for it below).
All of our day calculators are measured and QA'd by our engineer. Read more about the Git process here. But here's how 40 days ago gets calculated on each visit:
40 days is Thursday March 20, 2025 or could be if you only want workdays. This calculation takes 40 days and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Thursday March 20, 2025 date.
