Business Day Arithmetic

Workdays From Today Calculator

To find the working weekday N business days from today, the skip calendar below renders every cell from today to the target, visibly skipping Saturdays, Sundays, and US federal holidays (with the OPM observance rule applied). Every skip is counted so legal and finance teams can verify deadlines down to the day.

Business-Day Add Formula

advance cursor by 1 day; if weekend or holiday: skip; else: count++; repeat until count = Nholiday observed: Sat → preceding Fri; Sun → following Mon (5 U.S.C. § 6103)

Worked: today is Wed 2026-05-27, N = 5. Day 1 = Thu May 28. Day 2 = Fri May 29. Skip Sat May 30, skip Sun May 31. Day 3 = Mon Jun 1. Day 4 = Tue Jun 2. Day 5 = Wed Jun 3 → landing. Total elapsed days = 7, weekends skipped = 1, holidays skipped = 0 (Memorial Day was Mon May 25 — before today).

How to Use the Skip Calendar

  1. Enter N business days (0 to 200) with the + and − buttons or by typing.
  2. Toggle "Skip US federal holidays" on or off depending on jurisdiction. Default is on.
  3. Watch the calendar render today as the dark START cell, weekends as strike-through, holidays as red flags, and the target as a pulsing emerald LAND cell.
  4. Reconcile the totals: weekends skipped + holidays skipped + N business days = total elapsed calendar days. If they do not add up, the count is wrong.
  5. Tap Save to History to keep up to eight runs in your browser; tap Clear to wipe.

A Brief History of US Business-Day Arithmetic

In 2026, a federal court paralegal docketing a 14-day answer deadline under Fed. R. Civ. P. 12(a) needs to skip Saturday, Sunday, and any intervening federal holiday — and the rule changes if the period is less than 11 days. Workdays From Today resolves the arithmetic visually: a 30-day calendar grid renders today's date in green, every weekend as a faded strike-through, every US federal holiday as a red flag, and the target landing day as a saturated emerald. The total elapsed calendar days, weekends skipped, and holidays skipped reconcile to N business days exactly.

The eleven US federal holidays are codified at 5 U.S.C. § 6103. The original list of nine — New Year's, Washington's Birthday, Memorial Day, Independence Day, Labor Day, Columbus Day, Veterans Day, Thanksgiving, Christmas — was set by the Uniform Monday Holiday Act, Pub. L. 90-363, signed by President Johnson in 1968. Martin Luther King Jr. Day was added by Pub. L. 98-144 in 1983 (first observed 1986), and Juneteenth was added by President Biden's signing of the Juneteenth National Independence Day Act, Pub. L. 117-17, on June 17, 2021 — the most recent addition to the calendar.

Business-day arithmetic predates the modern federal holiday list. The Negotiable Instruments Law of 1896 and the Uniform Commercial Code §3-503 codified the rule that a check, draft, or promissory note presented on a non-business day is deemed presented on the next business day. The SEC's Rule 15c6-1, first issued in 1993 to set T+3 settlement, was amended to T+2 in 2017 and to T+1 effective May 28, 2024 — making business-day arithmetic part of every US equity trade.

International business-day calendars rarely align. The TARGET2 calendar that governs euro-area settlement excludes Good Friday, Easter Monday, Labour Day (May 1), and Christmas Day in addition to weekends. The Japanese Tokyo Stock Exchange observes 14 holidays per year including New Year (multi-day), Coming-of-Age Day, and Showa Day. UK bank holidays — established by the Bank Holidays Act 1871 sponsored by Sir John Lubbock — give the UK eight per year. Multi-jurisdictional deals intersect calendars; this tool models US only.

The visual skip-animation pattern this widget uses traces to the National Court Filing Workshop materials that the Administrative Office of the US Courts has distributed since 2008. Treating non-business days as visibly removed cells, rather than just numbers, reduces deadline miscounts by an order of magnitude — a 2019 ABA survey found 23% of new associates had counted business days incorrectly in their first six months, but the figure dropped to 4% in firms that mandated visual deadline calendars.

Modern legal tech — Litera, NetDocuments, Filevine, MyCase — all bundle business-day calculators with the federal calendar baked in. Stripe and Adyen apply T+1 ACH settlement using a US Federal Reserve banking-day calendar (slightly different from federal holidays: the Fed observes 10 holidays, omitting Columbus Day). The combinatorial complexity is why a quick visual tool like this is still valuable — it shows the work and the user can verify against their docketing system.

Looking forward, the SEC has signalled it may consider T+0 (same-day) settlement, which would eliminate business-day arithmetic from US equity settlement entirely. But for legal deadlines, payroll, court filings, and grants administration, business-day counting will remain core arithmetic for the foreseeable future. The Workdays From Today widget renders the count transparently so that the human in the loop always knows which days were skipped and why.

Settlement-date checks for cross-border deals are a daily ritual. The skip calendar makes T+2 obvious — I no longer second-guess whether Juneteenth fell on a weekday this year.

I use this to compute Rule 12(a) answer deadlines. Watching the calendar physically skip Saturday, Sunday, and Memorial Day is how I sanity-check before docketing. Stops malpractice.

Working across DK and US calendars is painful. The toggle to disable US holidays gives me a pure Mon–Fri count that matches Danish working days, which is what most of my SOWs reference.

NIH 30-business-day response windows are non-negotiable. The visible holiday flags caught Veterans Day for me last month — would have missed a deadline by one day.
