How to use it
- Choose What to find: count the days between two dates, or add working days to a date.
- Type the Start date. In count mode, type the End date too, and tick the include boxes if the first or the last day should count.
- Choose the Country. For Germany, also choose the State (Land), because each Land has its own holidays.
- Read Working days, then open Holidays in the period to see which holidays were skipped and which of them are half days.
How working days are counted
A working day is a day that is neither a weekend day nor a full public holiday. Saturday and Sunday are the weekend in every country except Saudi Arabia, where it is Friday and Saturday. Saturday counts as a weekend day unless you tick Saturday is a working day, which suits shops and employers who open on Saturdays; in Saudi Arabia, ticking it leaves Friday as the only weekend day.
A half-day holiday, the arife (the eve of a religious holiday, and the afternoon of 28 October in Turkey), is still a working day. Public offices close from 13:00, but the day itself is not a holiday, so it does not reduce the count.
Working days = Calendar days − Weekend days − Full public holidays on working days- Calendar days: every day of the period, with the start and end days included or left out as ticked.
- Weeks: calendar days divided by seven, shown with one decimal.
Days between two dates
With the end date left out, the calendar days are the plain difference between the two dates: from 16 March to 1 April is 16 days. With both dates counted, the number is one higher, because both ends are part of the period.
Contracts, notice periods and legal deadlines often count days in their own way. This calculator gives the arithmetic; the rule in the contract or the law decides what counts.
Public holidays by country
Türkiye: the fixed holidays and the religious holidays of 2025 to 2027. The fixed holidays come from Law No. 2429; the religious dates come from the Diyanet calendar. The 2027 religious dates are marked as expected, because the moon decides them and they can move by a day.
The Turkish data also lists the Saturday after a holiday that ends on a Friday, for example 2 May 2026 after 1 May and 2 January 2027 after 1 January. The data cites article 2 of Law No. 2429 for it. The Saturday reduces the working days only when Saturday is a working day.
United States: federal holidays and their observed dates, from OPM. A holiday that falls on a Saturday is observed on the Friday before, and one that falls on a Sunday on the Monday after. State and city holidays are not included.
United Kingdom: England and Wales bank holidays from GOV.UK, including substitute days. Scotland and Northern Ireland have other bank holidays and are not included.
Germany: the national holidays, plus the holidays of the Land you choose, from the Land holiday laws (Feiertagsgesetze).
France: the eleven public holidays of metropolitan France under the Labour Code (article L3133-1). The two extra holidays of Alsace-Moselle are not included.
Spain: the national holidays that apply in every region, from the BOE. Regional holidays are not included.
China (mainland): every day off of the State Council's holiday notices for 2025, 2026 and 2027, and the make-up working days (a Saturday or Sunday that is a working day). Make-up days count as working days and are listed. Hong Kong, Macau and Taiwan are not included.
What this calculator does not include
- Administrative leave that a government announces for public employees. Such leave is announced in the Official Gazette or by official notice, and this page cannot know it in advance.
- Company closures, collective agreements and local holidays.
- Any year before 2025 or after 2027 when a holiday country is chosen. Choose None as the country to count weekends only for those years.
Worked example: 16 March to 1 April 2026 in Turkey
With the default settings the start date is 16 March 2026 and the end date is 1 April 2026, which is not counted. The period runs from Monday 16 March to Tuesday 31 March: 16 calendar days.
Four of them are weekend days: 21 and 22 March, and 28 and 29 March. On Friday 20 March the first day of Ramazan Bayramı is a full holiday, so it takes a working day off. Thursday 19 March is the arife: a half day, so it stays a working day.
That gives 16 − 4 − 1 = 11 working days. Switching to add mode with 10 working days from 16 March gives Tuesday 31 March 2026.
| Result | |
|---|---|
| Calendar days | 16 |
| Weekend days | 4 |
| Public holidays on working days | 1 |
| Working days | 11 |
| Weeks | 2.3 |
Frequently asked questions
Why is the end date not counted by default?
Without it, the result is the plain difference between the two dates, which is how most people count the days between them. Tick Count the end date when the last day of the period should count, such as the final day of a leave period.
Are half-day holidays counted as working days?
Yes. An arife is a half day: public offices close from 13:00, but the day stays a working day. It is listed with Half day set to Yes and does not reduce the working days.
Why does Saturday count as a weekend day?
Many offices are closed on Saturdays, so the default follows that. Tick Saturday is a working day if your employer, your shop or your contract works on Saturdays; a Saturday holiday then reduces the count. Saudi Arabia is the exception: its weekend is Friday and Saturday.
Are holidays announced later included?
Not automatically. The calculator uses the holiday data of 2025 to 2027 built into the tool. Administrative leave that a government announces later, and holidays decided after the data was checked, are not in it.
Can I count days in 2028 or later?
Yes, with the country set to None, which counts weekends only. For a country with holidays the data ends on 31 December 2027, and the page then shows a message instead of a result.
Is the result binding for a contract or a tax deadline?
No. The result is a calculation for planning. A contract, a court or a tax office applies its own rule for days and holidays, and that rule decides the final date.
Are the dates I enter sent anywhere?
No. The calculation runs in your browser, and nothing you type is sent to us or saved by the page.
