39 days ago from today was 17 Feb 2025, a Monday. As we approach calculations over month in the past, the 31 days in March play significant roles, alongside the day of the week. Since today is Friday, well need to account for the weekend if you care about work days. If not, the calculation will remain the same. Counting backwards from today skips several weekends, meaning that subtracting 39 days takes us from the end of of March to potentially crossing far beyond March or February. For those of us focusing on workdays, subtracting 39 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 39 days ago gets calculated on each visit:
39 days is Monday February 17, 2025 or could be if you only want workdays. This calculation takes 39 days and only subtracts by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Monday February 17, 2025 date.
