Calculate the public holidays falling between two dates in a chosen jurisdiction, including substitute days. The calculator runs entirely in your browser and pairs a focused answer with the method, assumptions and the related tools worth checking next.
Your inputs stay in this browser tab. Nothing is sent to a server to produce the result.
Review the inputs and select Calculate.
Enter a start date, an end date and one of the holiday calendars listed in the form — for example United States (federal) or United Kingdom — England & Wales. The calculator lists every public holiday its rules place inside the range and counts them, showing how many fall on a working day under the weekend pattern you choose and how many are substitute days.
Each calendar is generated from rules — fixed dates, nth-weekday rules such as the third Monday of January, and Easter-linked rules — rather than a printed list of dates, so any year can be computed. Where a jurisdiction observes a holiday on a different day when it falls at a weekend, the engine applies that substitute day and flags it in the count.
From January 1 to January 31, 2026, the United States (federal) calendar gives 2 public holidays: New Year’s Day on January 1 and Martin Luther King Jr. Day on January 19. Both fall on weekdays, so with a Saturday-and-Sunday weekend both count as falling on a working day, and there are no substitute days.
In July 2026 the same calendar returns a single entry: Independence Day falls on a Saturday, so it is observed as a substitute day on Friday, July 3. The calendars cover only the jurisdictions named in the form — on the United States calendar, state and local holidays are not included — and the working-day count changes with the weekend pattern you select.
Enter the date range and holiday calendar, then select Calculate. Each step below is a short action rather than a wall of explanation.

Two on the United States (federal) calendar: New Year's Day on Thursday 1 January and Martin Luther King Jr. Day on Monday 19 January. Both fall on weekdays, so with a Saturday-and-Sunday weekend both count as holidays falling on a working day, and there are no substitute days.
When a holiday falls at a weekend, some jurisdictions observe it on a nearby working day instead. In July 2026 the United States calendar returns a single entry: Independence Day falls on Saturday 4 July, so it is observed as a substitute day on Friday 3 July, and the calculator flags it as a substitute in the count.
Each calendar is generated from rules rather than read from a printed list of dates — fixed dates, nth-weekday rules such as the third Monday of January, and Easter-linked rules — so the holidays can be computed for any year your range covers.
No. The calendars cover only the jurisdictions named in the form. The United States calendar is the federal one, so state and local holidays are not included — choose the calendar that matches the place you are planning around.
It decides how many of the holidays count as falling on a working day. The calculator reports the holidays in your range together with how many land on working days under the pattern you choose, so the same range can show a different working-day split when the pattern changes.
