    Calculate the deadline.

    Pick a ready-made period or type your own. The last day is found under HMK art. 92 and 93, and the judicial recess option applies the art. 104 extension; the holiday calendar covers 2024–2030.

    Period details

    Basis of the period: HMK art. 345/1

    Two weeks from the proper service of the judgment. For each party the period starts with that party’s own service.

    Enter a whole number from 1 to 104. You confirm the period from the relevant statute.

    When on, a period that ends between 20 July and 31 August is extended by one week from the day the recess ends (HMK art. 104). For the urgent matters in HMK art. 103 (such as interim injunctions and attachments, maintenance, employee claims, bankruptcy and concordat) courts work during the recess and periods are not extended; switch the option off for those matters.

    How the period is calculated

    For legal periods the tool applies the common rules of Turkish procedural law in order: first the raw end, then the holiday rollover, and last the judicial recess extension. The steps are listed in the result card, and the same steps play out day by day on the calendar.

    Rules applied

    1. 1/5

      Days, weeks, months and years (HMK art. 92)

      In a period set in days the start day is not counted, and the period ends at the end of the last day. A period set in weeks, months or years ends on the day of the last week, month or year that corresponds to the start day. When the ending month has no corresponding day, the period ends on the last day of that month: a one-month period starting on 31 January ends on the last day of February. The Enforcement and Bankruptcy Code art. 19 and CMK art. 39 follow the same method.

    2. 2/5

      A last day on a holiday (HMK art. 93)

      Public holidays are part of the period and are not skipped when counting. If the last day falls on a public holiday, the period ends at the end of working hours on the first working day after the holiday. Weekends are treated like holidays; when a religious holiday and a weekend run together, the period rolls over to the first working day. The holiday table, including the 2024–2030 religious holidays, is below.

    3. 3/5

      Judicial recess (HMK art. 102–104)

      The judicial recess starts on 20 July and ends on 31 August. In matters subject to it, a period that ends during the recess is deemed extended by one week from the day the recess ends, which means 7 September. If 7 September is a weekend or a holiday, the period rolls over to the first working day. The “This matter is subject to the judicial recess” option switches this on and off. The period does not extend in the urgent matters listed in HMK art. 103 (such as interim injunctions and attachments, maintenance, employee claims, bankruptcy and concordat).

    4. 4/5

      Holiday eves (arife)

      The eves of Ramazan Bayrami and Kurban Bayrami and 28 October are half-day holidays (Law no. 2429). Whether a last day falling on an eve extends the period is disputed in practice. The tool does not roll the date over; it shows a warning with the result and suggests filing before noon on the eve as a precaution.

    5. 5/5

      Business-day mode

      Some administrative and contractual periods are counted in business days. In this mode counting starts on the day after the start date and Saturdays and Sundays are always skipped; with the option on, the fixed public holidays, the 3 days of Ramazan Bayrami and the 4 days of Kurban Bayrami are skipped too. This is the same business-day count as in HukukBis case management software. The judicial recess is not applied in this mode.

    The holiday calendar covers 2024–2030. If the end or a rollover day falls outside that range, the tool does not guess; it returns an error message.

    Examples: appeal period and judicial recess

    The four examples were calculated with the same engine as the tool; try your own dates in the form above.

    1. A two-week appeal that meets a religious holiday

      For a decision served on Friday, May 15, 2026, the two-week appeal period runs out on Friday, May 29, 2026, which falls in Kurban Bayrami. A weekend follows the holiday, so the period ends at the end of working hours on Monday, June 1, 2026, the first working day.

    2. A period that meets the judicial recess

      In a matter subject to the judicial recess, a decision served on Friday, July 10, 2026 has a two-week period that runs out on Friday, July 24, 2026, inside the recess. Under HMK art. 104 the period is extended by one week from 31 August, when the recess ends, so the due date is Monday, September 7, 2026.

    3. End of the month

      For a one-month period starting on Saturday, January 31, 2026, February has no matching day, so the period runs out on the last day of February, Saturday, February 28, 2026. That day is a weekend, so the due date is Monday, March 2, 2026.

    4. Business-day mode

      A 1 business day period starting on Thursday, March 19, 2026: the next day is the first day of Ramazan Bayrami and the weekend that follows is skipped too, so the due date is Monday, March 23, 2026. Had the holiday not been skipped, the result would be Friday, March 20, 2026.

    What is out of scope

    • Service rules and how the service date is determined; the calculation takes the start date as entered.
    • Periods set by a judge and statutory extensions such as the extra time for a statement of defence.
    • Special-law provisions that change when a period starts or how long it is; confirm the ready-made periods against the statute.
    • A firm rollover for holiday eves; only a warning is shown.
    Responsibility note

    This tool is a calculation aid for information only; it is not legal advice and its result must not be used as a binding determination of a deadline. The final decision is the lawyer’s. Service rules, how the service date is determined, the effect of holiday eves, statutory extensions and file-specific conditions are out of scope. Checking the type of period, the start date and the accuracy of the result against the legislation is the user’s responsibility. Always verify the period separately before acting on a calculated date.

    Questions

    What do people ask about deadline calculation?

    Is the appeal period 14 days or two weeks?

    In civil procedure the appeal period is two weeks (HMK art. 345). Because it is set in weeks, it ends on the day that corresponds to the day of service. Use the “Civil appeal” ready-made period or enter 2 weeks; entering 14 business days gives a wrong result.

    What happens if the last day falls on a holiday or weekend?

    Public holidays are part of the period, but if the last day is a holiday the period ends at the end of working hours on the first working day after it (HMK art. 93). The tool applies this to weekends and to the 2024–2030 public and religious holidays, and shows the days it rolled over.

    Is the judicial recess taken into account?

    Yes, as an option. With “This matter is subject to the judicial recess” on, a period that ends between 20 July and 31 August is extended by one week from the day the recess ends (HMK art. 104); a period ending on 24 July, for example, moves to 7 September. The urgent matters in HMK art. 103 are not extended, so switch the option off for them.

    Are holiday eves taken into account?

    The tool does not roll an eve over. If the last day is a half-day eve it shows a warning; whether the eve extends the period is disputed in practice, so filing before noon on the eve is suggested as a precaution.

    What happens with periods that end at the end of a month?

    If a period is set in months and the ending month has no day matching the start day, it ends on the last day of that month (HMK art. 92/2). A one-month period starting on 31 January ends on the last day of February, 28 February in 2026; if that day is a weekend, the end rolls over to the first working day.

    When should I use business-day mode?

    Some administrative and contractual periods are counted in business days. In this mode Saturdays and Sundays, and optionally public holidays, are skipped and the start day is not counted. For statutory procedural periods such as appeal, cassation and objection, use the calendar units (days, weeks, months).

    Can I calculate for 2031 and later?

    The holiday calendar covers 2024–2030. When the end or a rollover day falls outside that range the tool returns an error rather than guessing. In business-day mode, if you switch off the holiday option only weekends are skipped and no year limit applies.

    Is the result binding?

    No. The result is a calculation aid, not a binding determination of a deadline or a legal opinion; the final decision is the lawyer’s. Verifying the start date, the period and its type against the legislation is up to the user.

    Does the product use the same rules?

    The legal deadline records on HukukBis case files calculate the due date with the day, week, month and year rules, the holiday rollover and the judicial recess extension this tool applies. In the product you attach the deadline to a case and follow it with a countdown in the agenda; details are on the legal deadline tracking page.
