90 days ago from today was 15 Feb 2025, a Saturday. Calculating time over multiple months means we must count back weeks and weekends + the 31 May, typically moving from the middle of May into April and potentially further. 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. The key difference with subtracting two+ months, compared to shorter spans, is the need to consider several weekends from the middle of May to get Saturday February 15, 2025.
All of our day calculators are measured and QA'd by our engineer. Read more about the Git process here. But here's how 90 days ago gets calculated on each visit:
90 days is Saturday February 15, 2025 or could be if you only want workdays. This calculation takes 90 days 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 15, 2025 date.
