It’s always a good idea to check out Turkey’s and Istanbul’s official, public, national, regional and religious holidays before planning a trip or a sightseeing excursion. To make it easier for you I created this nice overview. Please pay special attention to the religious holidays since they change yearly.
Most popular tourist atrractions and shops open their doors during national holidays, but are closed until 13:00 on the first day of religious holidays. Both the Spice Bazaar and the Grand Bazaar are closed for the full duration of religious holidays, and also on October 29th. Banks are closed during all holidays — national and religious.
Avoid road trips during both religious holidays, especially the Feast of the Sacrifice , because traffic intensifies dramatically. This is because during these holidays Turks visit their relatives all over the country. Also please note that May 1 demonstartions in and around Taksim often end quite agitated. Don’t take unnecessary risks, and avoid crowded areas such as Taksim, Nişantaşı, Beşiktaş and Kadıköy on May 1st.
