Turkey observes a number of public holidays, including both religious festivals and secular commemorations. The dates of some holidays can vary from year to year because they are based on the lunar Islamic calendar or other variable schedules. Here is a list of some of the key public holidays in Turkey for 2025:

1. New Year's Day: January 1st

2. International Women's Day: March 8th

3. National Sovereignty and Children's Day: April 23rd

4. Labour Day: May 1st

5. Commemoration of Atatürk, Youth and Sports Day: May 19th

6. Ramazan Bayramı (Eid al-Fitr): The end of Ramadan, date to be determined based on the sighting of the new moon.

7. Kurban Bayramı (Eid al-Adha): The festival of sacrifice, date to be determined based on the sighting of the new moon.

8.  Victory Day: August 30th

9. Republic Day: October 29th

Please note that the dates for the Islamic holidays (Ramazan Bayramı and Kurban Bayramı) are not fixed and depend on the sighting of the crescent moon, which is used to determine the beginning and end of religious months. The exact dates for these holidays are typically announced by the Turkish General Directorate of Inspection Affairs after consulting with religious authorities.

Additionally, Turkey has other holidays that are not included in this list, and some holidays may be observed with half-day working hours or may be moved to a nearby weekend if they fall on a weekend day. It's always a good idea to check the official government calendar or local announcements for the most current and complete list of holidays in Turkey.
