There are 21 business days between June 1 and June 30, 2026, once the eight weekend days in that 29-day span are excluded.
Weekends are always skipped. Holidays are skipped only when the box is ticked. Results computed in your browser.
A shipping estimate quoted as a range needs two separate calculations, not one. Run this tool in add mode with 5, then again with 7, and you get the earliest and latest dates a shipment window actually spans, holidays included if you tick that box.
The federal holiday calendar set by law has eleven fixed dates. When one lands on a Saturday, it's observed the Friday before; a Sunday holiday is observed the following Monday. This tool applies that observed-date rule automatically whenever the holiday box is ticked.
| Holiday | When |
|---|---|
| New Year's Day | January 1 |
| Birthday of Martin Luther King, Jr. | Third Monday in January |
| Washington's Birthday | Third Monday in February |
| Memorial Day | Last Monday in May |
| Juneteenth National Independence Day | June 19 |
| Independence Day | July 4 |
| Labor Day | First Monday in September |
| Columbus Day | Second Monday in October |
| Veterans Day | November 11 |
| Thanksgiving Day | Fourth Thursday in November |
| Christmas Day | December 25 |
A 2-week notice period reliably contains 10 weekdays only when no observed holiday falls inside it. Add a Thanksgiving or a Christmas to the span, tick the holiday box, and the same two calendar weeks yields 9 business days instead of 10. This is exactly the kind of gap that catches people off guard around November and December deadlines.
Only the eleven federal holidays are built into this calculator. A company floating holiday, a state-only holiday, or a regional observance is not in that set, and if one of those falls inside your range, you'd need to subtract it by hand. For a full year or month's worth of business days as a planning figure, most years hold 260 to 262 weekdays total, and the federal set removes roughly 11 more from that, landing near 249 to 251 working days, though the exact number shifts depending on which day of the week January 1 falls on.
Here is the calculator's add mode doing its worst-case work. Start on Wednesday, November 25, 2026 and add 5 business days with the holiday box ticked. Thursday the 26th is Thanksgiving, skipped. Friday the 27th is day one. Saturday and Sunday don't count. Monday the 30th is day two, then December 1, 2, and 3 finish the count. The answer lands on Thursday, December 3, 2026, a full eight calendar days after the start. Untick the holiday box and the same input lands a day earlier. That one-checkbox difference is the entire gap between "5 business days" as a shipper counts it and as a calendar counts it.
In 2026, Independence Day lands on a Saturday, so the federal observance moves to Friday, July 3, and that Friday is the day this calculator removes when holidays are on. The same shift happens in reverse for Sunday holidays, observed the following Monday. It changes results in ways that surprise people: a holiday can knock out a business day even though the holiday itself sits on a weekend that was never going to count.
The count of 21 business days between June 1 and June 30, 2026 quoted at the top of this page excludes weekends only. Tick the holiday box and it drops to 20, because Juneteenth falls on Friday, June 19 in 2026, a weekday that would otherwise have counted. A one-day slip like that is invisible until a payment or a filing shows up late, which is the argument for running any June, July, November, or December deadline through this tool twice, once with each setting, and seeing whether the answer moves.
The generic rules above ("third Monday," "last Monday") resolve to these actual dates in 2026. Only one of the eleven needs shifting this year: Independence Day falls on a Saturday, so federal offices close Friday, July 3 instead. Nothing lands on a Sunday in 2026, which means no Monday observances at all.
| Holiday | 2026 date | Day off work |
|---|---|---|
| New Year's Day | Thu, Jan 1 | Thu, Jan 1 |
| Birthday of Martin Luther King, Jr. | Mon, Jan 19 | Mon, Jan 19 |
| Washington's Birthday | Mon, Feb 16 | Mon, Feb 16 |
| Memorial Day | Mon, May 25 | Mon, May 25 |
| Juneteenth | Fri, Jun 19 | Fri, Jun 19 |
| Independence Day | Sat, Jul 4 | Fri, Jul 3 |
| Labor Day | Mon, Sep 7 | Mon, Sep 7 |
| Columbus Day | Mon, Oct 12 | Mon, Oct 12 |

For annual planning: 2026 runs 365 days, which is 52 full weeks plus one extra day, and since the year opens on a Thursday that extra day is a Thursday too. So the year holds 261 weekdays, and taking out the eleven observed holidays leaves 250 federal working days. One housekeeping note on the calculator itself: it builds its holiday list for the current calendar year and the next one, so a range set several years out is a weekend-only count even with the box ticked.
When a contract promises action within some number of business days, three details decide the real date, and none of them are arithmetic. First, which day is day one: the usual reading starts the count on the first business day after the trigger, so a notice delivered Tuesday makes Wednesday day one. Second, what a delivery late in the day does: something received at 4:58 PM Friday often starts the clock Monday under a "received after close of business" clause. Third, and easiest to miss, whether the contract defines "business day" at all. A definition like "any day on which banks in New York are authorized to be open" is not the federal list; it is a different list that happens to overlap most of the year. Read the definitions section before trusting any calculator, this one included.
The Federal Reserve follows the eleven federal holidays, so wire transfers and ACH settlement pause on all of them. The New York Stock Exchange does not: it trades right through Columbus Day and Veterans Day, then closes for Good Friday, April 3 in 2026, which no US government treats as a holiday. The day after Thanksgiving, November 27 in 2026, is a full federal business day even though half the country's offices are dark and the market shuts early at 1:00 PM. States layer on their own closings too: Massachusetts and Maine courts close for Patriots' Day, the third Monday in April (April 20 in 2026), a date this calculator counts as an ordinary working Monday. If your deadline depends on a court, a bank, or an exchange, check that institution's calendar, because "business day" quietly means "day we are open."
Start on Friday, December 18, 2026 and add 10 business days. With the holiday box off, the count walks through the next two weeks of weekdays and lands on Friday, January 1, 2027. That is New Year's Day. Nobody is delivering, filing, or approving anything on it. Tick the box and the count skips both Christmas (Friday the 25th) and New Year's Day, landing instead on Tuesday, January 5, 2027, a full 18 calendar days after the start. So a vendor quoting "ten business days" in mid-December is really quoting two and a half weeks, and the version of that promise with holidays honored differs from the naive version by two working days. December and late June are the two stretches of the year where running this tool with the box on and off, and comparing, earns its thirty seconds.

Use add mode twice: once with 5 business days from your order date, once with 7, to get the earliest and latest expected delivery dates. Tick the holiday box if the window crosses a federal holiday.
Between-mode counting excludes the start date and includes the end date, the convention used for deadlines and shipping. If you expected both dates counted, or neither, the result will look off by exactly one day.
No, only the eleven US federal holidays are built in. A company floating holiday, or a state-only holiday, needs to be subtracted manually from the result if it falls inside your range.
It shifts to the observed date under the standard federal rule: a Saturday holiday is observed the preceding Friday, and a Sunday holiday is observed the following Monday, and the tool skips whichever day is actually observed.
Only if neither of the two weekends inside it contains an observed holiday and the period starts and ends on a weekday. Two calendar weeks reliably contains 10 weekdays, but a holiday inside that span would reduce the business-day count if you're also excluding holidays.
Just one. Independence Day falls on Saturday, July 4, so federal workers get Friday, July 3 off, and that Friday is the day this calculator removes. The other ten holidays all land on weekdays in 2026, and none fall on a Sunday, so there are no Monday shifts this year.
No. Friday, November 27, 2026 counts as a normal business day here and in federal deadline math, even though many private offices close and the stock market shuts at 1:00 PM. If the business you are waiting on treats it as a holiday, subtract one day from this tool's result by hand.
No. The Federal Reserve, and therefore most bank settlement, follows the eleven federal holidays. The New York Stock Exchange trades on Columbus Day and Veterans Day but closes for Good Friday, which is not a federal holiday at all. For payment or trading deadlines, check that institution's own calendar.
2026 contains 261 weekdays, since its 365 days make 52 weeks plus one extra Thursday. Subtract the eleven observed federal holidays, all of which land on weekdays this year, and you get 250 federal working days.
