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 99 weeks to today's date gets calculated on each visit:
Friday Friday March 20, 2026 is the 079 day of the year or 21.64% through 2026.
99 weeks is Friday March 20, 2026 or could be Monday December 21, 2026 if you only want workdays. This calculation takes 99 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 March 20, 2026 date.
