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 89 weeks to today's date gets calculated on each visit:
Friday Friday January 09, 2026 is the 009 day of the year or 2.47% through 2026.
89 weeks is Friday January 09, 2026 or could be Monday September 14, 2026 if you only want workdays. This calculation takes 89 weeks and only adds by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Friday January 09, 2026 date.
