100 business days from today is Thursday, February 11, 2027
Counting 100 working days from today and skipping weekends, the answer is Thursday, February 11, 2027. That spans 140 calendar days, because 40 weekend days were skipped along the way.
What is the difference between business days and calendar days?
A business day is any weekday, Monday to Friday. Weekends do not count, which is why 100 business days stretches across 140 calendar days rather than 100. As a rough guide, every five business days adds seven calendar days, so the gap between the two figures grows by about two days a week.
What about public holidays?
Federal holidays fall inside this range, so the answer changes depending on whether your agreement counts them. Excluding weekends only gives Thursday, February 11, 2027. Also excluding US federal holidays pushes it to Monday, February 22, 2027, 7 days later.
The holidays skipped are:
- October 12, 2026 – Columbus Day
- November 11, 2026 – Veterans Day
- November 26, 2026 – Thanksgiving Day
- December 25, 2026 – Christmas Day
- January 1, 2027 – New Year's Day
- January 18, 2027 – Martin Luther King Jr. Day
- February 15, 2027 – Presidents' Day
Federal holidays are the national set. State holidays, company shutdowns and observances in other countries are not included, so check your own calendar for anything contractual.
When do you need to count business days?
Business-day counting is the default in contracts, refund windows, notice periods, court filing rules and shipping estimates, precisely because it does not punish a deadline for landing on a weekend. The convention is almost always to exclude the starting day and count from the next working day, which is what this page does. If your agreement says "within 100 business days", February 11, 2027 is the usual reading, or February 22, 2027 if holidays are excluded too.
