Legal deadline calculator (objection, appeal, cassation)

How it is calculated

• Start. For a period in days the day of notification is not counted; the period starts the next day (Code of Civil Procedure [HMK] art. 92/1; Enforcement and Bankruptcy Code [İİK] art. 19/1; Criminal Procedure Code [CMK] art. 39/1; Administrative Procedure Code [İYUK] art. 8/1). The calculator takes the date you enter as that day.
• Weeks and months. A period in weeks ends on the same weekday in the last week; a period in months ends on the same day of the month, or on the last day of a shorter month (HMK art. 92/2; İİK art. 19/2; CMK art. 39/2–3).
• Holidays. Holidays count inside the period; if the last day is a holiday the period ends on the first working day after it (HMK art. 93; İİK art. 19/3; CMK art. 39/4; İYUK art. 8/2). The calculator treats Sundays, the general holidays of Law No. 2429 (1 January, 23 April, 1 May, 19 May, 15 July, 30 August, 29 October) and the Ramazan and Kurban Bayramı days of 2025–2027 as holidays; the bayram dates come from the lists of the Presidency of Religious Affairs (Diyanet).
• Judicial recess (adli tatil, 20 July – 31 August). Under the HMK a period that ends in the recess is extended by one week from the day the recess ends (arts 102–104), except in the matters listed in HMK art. 103/1. Under the CMK the extension is three days (art. 331/4) and under the İYUK seven days (arts 8/3 and 61/1). İİK has no extension for the recess, and it does not apply to reinstatement periods because employees’ claims are heard during the recess (HMK art. 103/1-ç).
• Electronic notification. A document sent by e-Tebligat is deemed notified at the end of the fifth day after it reaches the address (Notification Act art. 7/a). Tick the box and the calculator adds those five days.
• Safe date. If the Saturday rule or the recess extension moves the last day later, the earliest date that relies on neither is shown as well.

Example

In a civil case the judgment was served on Saturday, 7 November 2026. The appeal period is two weeks (HMK art. 345); because the day of service is not counted, it runs out on Saturday, 21 November 2026. Saturday is treated as a holiday, so the period ends on Monday, 23 November 2026 (HMK art. 93). The calculator also shows 21 November 2026 as the safe date that does not rely on the Saturday rule.

Main periods

Limitation periods

Limitation periods cannot be changed by contract (TBK art. 148). The day the period starts is not counted (art. 151). Limitation is suspended in some situations (art. 153) and interrupted in others (art. 154); this table does not show them.

What it leaves out

• Whether and when notification took place. The date a notice posted on the door counts as served (Notification Act art. 21), notices sent to an old address after a change of address (art. 35) and similar cases are not calculated. The date has to be checked in the service record and the file.
• Saturday. HMK art. 93, İİK art. 19 and CMK art. 39 say “holiday” and do not mention Saturday. The calculator treats Saturday as a holiday (Law No. 657 art. 99) and shows a safe date that does not rely on that.
• Administrative leave days. Days of administrative leave (bridge days) that the Presidency may give public employees are not treated as holidays; the texts read do not say how they affect procedural periods.
• Half-day eves. On the eve of a bayram and on 28 October the holiday starts at 13:00 (Law No. 2429 arts 1 and 2/B). The codes do not say when a period ends on those days; the calculator does not extend it and gives a warning.
• Dates without data. Holiday data are recorded for 1 January 2025 to 31 December 2027; if a period runs outside that range no result is given.
• Open readings. The sentence in CMK art. 331/4 that periods falling in the recess “do not run”, and detained cases; the words “seven days from the following date” in İYUK art. 8/3 (7 or 8 September). In both the calculator uses the earliest extended date and shows the safe date separately.
• Other periods. Restoration of a missed period (HMK arts 95–96, CMK arts 40–41), acts with a different period under special laws (tax, social security, objections to consumer arbitration decisions and others), İYUK art. 7/3 (notice by announcement) and art. 11 (request to the administration) are not calculated. For criminal decisions given before 1 June 2024 the earlier periods apply (CMK provisional art. 6).
• How limitation works. The periods in the table are not calculated; the grounds for suspension and interruption (TBK arts 153–154) and the limitation periods of the criminal law are examined separately.
