87 days from today is 12 Sep 2025, a Friday. Calculating over the equivalent days of a month means multiple weeks, multiple weekends and officially crossing into July from the middle of June. Since today is Tuesday and still part of the beginning of the week we won't need to add additional days into next week. Key difference with adding days that span a full month is that shorter calculations might only require counting days and possibly adjusting for a single weekend. Adding 87 days across June requires us to account for multiple weekends, work schedules, and the specific nuances of being in the middle of June jumping to July.
All of our day calculators are measured and QA'd by our engineer. Read more about the Git process here. But here's how adding 87 days to today's date gets calculated on each visit:
Friday Friday September 12, 2025 is the 255 day of the year or 69.86% through 2025.
87 days is Friday September 12, 2025 or could be Thursday October 16, 2025 if you only want workdays. This calculation takes 87 days and only adds by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Friday September 12, 2025 date.
