Current Time in Istanbul
Turkey — Europe/Istanbul
About Time in Istanbul
Istanbul operates on Turkey Time (IANA: Europe/Istanbul) at UTC+3 year-round. Turkey abolished daylight saving time in 2016, permanently adopting UTC+3 (what was previously summer time). The clocks have not changed since September 2016, when Turkey moved to what it calls 'permanent summer time.'
Istanbul is 8 hours ahead of New York during EST and 7 hours ahead during EDT. It is 3 hours ahead of London during GMT and 2 hours ahead during BST. Istanbul is on the same time as Moscow, as both cities are fixed at UTC+3. It is 6 hours behind Tokyo. Istanbul is uniquely positioned at the border of Europe and Asia, straddling the Bosphorus strait.
Turkey's decision to adopt permanent UTC+3 was controversial. Geographically, Istanbul (longitude 29 E) is better suited to UTC+2 (Eastern European Time), and solar noon now occurs at about 12:30 PM in summer but 1:30 PM in winter — meaning winter mornings are noticeably darker than they would be under UTC+2. The choice to stay on UTC+3 was made to maximize evening daylight, but it means sunrise in Istanbul does not occur until after 8:00 AM in late December and early January.
Time Facts
Istanbul is the only major city in the world that spans two continents — Europe and Asia — yet the entire metropolitan area uses a single timezone (UTC+3), so crossing the Bosphorus Bridge does not require adjusting your watch.
Turkey's adoption of permanent summer time (UTC+3) in 2016 means Istanbul is now always on the same time as Moscow, despite being over 1,700 km to the southwest — the alignment is coincidental, as both countries independently chose UTC+3.
The Hagia Sophia's massive sundial, installed during the Ottoman era, was calibrated to local Istanbul time — which historically differed from both European and Middle Eastern time systems until the Ottoman Empire adopted the Gregorian calendar and European time zones in 1926.
Istanbul's Grand Bazaar, one of the oldest and largest covered markets in the world, opens at 9:00 AM and closes at 7:00 PM Turkey Time — a schedule that has remained remarkably consistent for centuries despite timezone changes.
