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 90 weeks to today's date gets calculated on each visit:
Thursday Thursday January 15, 2026 is the 015 day of the year or 4.11% through 2026.
90 weeks is Thursday January 15, 2026 or could be Thursday September 24, 2026 if you only want workdays. This calculation takes 90 weeks and only adds by the number of workdays in a week. Remember, removing the weekend from our calculation will drastically change our original Thursday January 15, 2026 date.
