BUSINESS DAY CALCULATOR
This free business day calculator adds or subtracts working days from any date — skipping weekends and U.S. federal holidays — so you land on the date a deadline actually falls on, not the one a plain calendar count suggests.

💼 What "Business Days" Really Means for a Deadline
1️⃣ Does the Start Day Count?
Most U.S. rules that say "within 10 business days" start counting from the next working day, not the day the clock was triggered. That's the convention this tool uses: it begins counting the first business day after your start date. If a specific contract or court rule counts the start day itself, subtract one from your result — and when the wording is unclear, give yourself the earlier date.
🏛️ Federal Holidays Aren't Everyone's Holidays
This calculator skips the eleven U.S. federal holidays, which is what banks, courts and government deadlines usually follow. But your employer, shipping carrier or state office may close on different days — the Friday after Thanksgiving, Good Friday, or a state holiday — and may stay open on some federal ones. Check the specific calendar that governs your deadline before you rely on the count.
📅 The "Observed" Day Is the One That Moves Your Deadline
When a fixed-date holiday like July 4 or December 25 lands on a Saturday, federal offices take the Friday before off; when it lands on a Sunday, they take the Monday after. That shifted weekday — not the calendar date of the holiday — is the day that actually pushes a working-day deadline out. This tool already accounts for those observed shifts, which is exactly where hand-counting tends to go wrong.
🔔 Turn the Due Date Into Something You'll Act On
A deadline is only useful if it's somewhere you'll see it. Once you have the date, our free reminder tool drops it into your own calendar as a Google Calendar event or an iCal file, created entirely in your browser.
