Türkiye Working Days Calculator with Public Holidays

How to use

1. In What to calculate, choose the working days between two dates or adding working days to a date.
2. Enter the Start date. Between two dates this day counts; when adding working days, the count starts the next day.
3. Between two dates, enter the End date; it counts too. When adding, enter the Working days to add.
4. Under More options, choose whether Saturday is a working day, how the half days on the eves and 28 October count, and whether administrative leave days are off.
5. Press Calculate. The result lists every date taken off the working days in a table.

Formula

• working days = calendar days − weekend days − public holidays − administrative leave
• public holidays = full-day holidays + half-day holidays × 0.5

Calendar days are all the days in the range, the start and the end day included. Weekend days are Saturdays and Sundays; with Saturday as a working day, only Sundays. Public holidays are the holidays that fall on weekdays: a feast day on a weekend is not taken off a second time. A half-day holiday is a holiday eve or 28 October, off from 1 pm; it takes 0.5, 0 or 1 day, as you choose. Administrative leave comes off only when you choose it.

When adding working days, the calculator counts the days one by one and gives the day the total reaches your number. With a half day on the way, the total can pass your number by half a day.

Worked example

The example on the page counts the whole of 2026, from 1 January to 31 December. The steps give the calendar days, the weekend days, the holidays on weekdays and the working days. The table shows every date taken off, the days of Ramazan and Kurban Bayramı included.

Limits

The calculator removes the national public holidays. It does not remove holidays of one province or institution, such as a local liberation day, or days off for bad weather. The feast dates come from Diyanet’s calendar; the public holidays by year start in 2005 and run to the last year in the data. Legal deadlines (lawsuits, objections, notices) have their own rules, which the calculator does not apply. Hours and shifts are not used.
