💡 Why does the time difference between Istanbul and Europe change throughout the year? Most European countries observe daylight saving time (DST): clocks go forward one hour on the last Sunday in March and back on the last Sunday in October. Turkey does not. Therefore: in winter (late October–late March), Istanbul is 3 hours ahead of London (TRT UTC+3 vs GMT UTC+0) and 2 hours ahead of Paris/Berlin (TRT UTC+3 vs CET UTC+1); in summer (late March–late October), Istanbul is 2 hours ahead of London (TRT UTC+3 vs BST UTC+1) and only 1 hour ahead of Paris/Berlin (TRT UTC+3 vs CEST UTC+2). The current difference is: … vs London.

A brief history of Istanbul
- 657 BC – 330 AD Greek colonists from Megara founded Byzantium around 657 BC on the promontory commanding the Bosphorus and the Golden Horn — a strategically exceptional position for trade and defence. The city flourished as a hub on the maritime routes between the Aegean and the Black Sea, falling successively under Persian, Athenian, Spartan and Macedonian influence, before the Romans incorporated it into their Empire in the 1st century AD.
- 330 – 1453 On 11 May 330, Emperor Constantine I formally refounded the city as Constantinople — the “New Rome” — making it the capital of the Eastern Roman (Byzantine) Empire. For more than a millennium it was the largest and wealthiest city in the Christian world. Hagia Sophia (537 AD), the Hippodrome, the Imperial Palaces and the great Theodosian Walls were built during this era. On 29 May 1453, Ottoman sultan Mehmed II captured the city after a 53-day siege, marking the fall of the Byzantine Empire.
- 1453 – 1923 Under the Ottoman Empire, the city — now called Kostantiniyye or Istanbul — became capital of an empire stretching from Vienna to Baghdad. Hagia Sophia was converted into a mosque. Topkapı Palace served as the sultans’ residence for four centuries. Between 1453 and 1600, Istanbul was probably the largest city in the western world. The Ottoman Empire collapsed after World War I and the city was occupied by Allied forces between 1918 and 1923.
- 1923 – Present The Republic of Turkey was proclaimed on 29 October 1923, with Ankara as its new capital. Istanbul retained its role as Turkey’s economic, cultural and tourism engine. In 2010, it was named a European Capital of Culture. The opening of the new Istanbul Airport in 2018 — one of the world’s largest — confirmed its status as a global hub. The city today exceeds 15 million inhabitants and welcomes over 18 million foreign tourists annually.

Top tourist attractions in Istanbul
🕌
Hagia Sophia (Aya Sofia)
A masterpiece of Byzantine architecture built between 532 and 537 AD by Emperor Justinian I. For nearly a thousand years the world’s largest cathedral. Converted to a mosque in 1453, turned into a museum in 1934, and reopened as a mosque in 2020. Its 55-metre dome remains one of history’s greatest engineering achievements.
🏰
Topkapı Palace
Home of the Ottoman sultans for 400 years (1465–1856), now one of the world’s most visited museums. Houses extraordinary treasures including the Spoonmaker’s Diamond (86 carats), the Imperial Harem, Islamic relics, and sweeping panoramic views of the Bosphorus and the Golden Horn.
🕊️
Blue Mosque (Sultan Ahmed)
Built between 1609 and 1616 under Sultan Ahmed I, the Blue Mosque is unique for its six minarets. The interior is lined with over 20,000 blue Iznik ceramic tiles. Directly opposite Hagia Sophia, together they form the most iconic skyline in Istanbul.
🛍️
Grand Bazaar (Kapalıçarşı)
One of the oldest and largest covered markets in the world, with 4,000 shops, 61 streets and more than 250,000 visitors per day. Founded in 1461, just after the Ottoman conquest. Carpets, jewellery, spices, ceramics, leather — a total sensory experience. The nearby Egyptian Bazaar (Spice Bazaar) is the best spot for spices and Turkish sweets.
⛵
Bosphorus — cruise between two continents
The Bosphorus Strait separates and connects Europe and Asia at just 700 m at its narrowest point. A cruise offers unforgettable views of waterfront Ottoman palaces (yalı), medieval fortresses (Rumelihisarı) and suspension bridges. A daily commuter ferry (vapur) crossing costs just a few Turkish lira — the most authentic Istanbul experience.
🏛️
Basilica Cistern (Yerebatan Sarayı)
One of Istanbul’s great subterranean surprises — a 6th-century cistern capable of storing 80,000 m³ of water, supported by 336 marble columns. Built by Justinian I, it supplied the Imperial Palace for centuries. The Medusa-head column bases are iconic. Atmospheric lighting and reflections on the water create an almost surreal setting.

Turkish cuisine — what to eat in Istanbul
Kebab & Döner
The symbol of Turkish gastronomy. Döner kebab — lamb or chicken grilled on a vertical rotisserie, served in lavash or pita. Adana kebab — spiced minced meat on a skewer. İskender kebab — döner topped with tomato sauce and melted butter, originating from Bursa but beloved in Istanbul. Available everywhere from street stalls to high-end restaurants.
Balık Ekmek & Meze
Balık ekmek (grilled fish sandwich) is Istanbul’s iconic street food, bought straight from boats moored at Galata Bridge. Meze are cold and warm starters: hummus, cacık (yoghurt with cucumber), muhamara, dolma — perfect alongside rakı, Turkey’s anise-flavoured national spirit.
Börek & Simit
Börek — flaky yufka pastry filled with cheese, meat or spinach — is Turkey’s universal snack, eaten for breakfast or on the go. Simit — a circular sesame-crusted bread ring, crispy outside and soft inside — is sold by street vendors all over Istanbul. Simit with strong black tea is the quintessential Istanbul breakfast.
Baklava & Sweets
Baklava — thin yufka layers alternating with pistachio or walnut, drenched in honey syrup — is the masterpiece of Ottoman patisserie. Turkish Delight (lokum) — gelatinous cubes with pistachio, rose or lemon — is the perfect edible souvenir. Kazandibi and sütlaç (Turkish milk puddings) round off the dessert menu.
Tea & Turkish Coffee
Turkey is one of the world’s great tea cultures. Çay (black tea) is drunk from tulip-shaped glasses dozens of times a day — the universal accompaniment to conversation. Turkish coffee (türk kahvesi) — finely ground, brewed in a cezve, served with grounds in a small cup — is a UNESCO Cultural Heritage since 2013. Sip slowly with a glass of water.
Kahvaltı — Turkish Breakfast
Kahvaltı is a proper feast: assorted cheeses, olives, fried eggs, tomatoes, cucumbers, honey, butter, jam and simit with tea. Istanbul has cafes dedicated exclusively to kahvaltı, some offering dozens of dishes. A Turkish weekend breakfast is a social event lasting 2–3 hours.

Practical information — Istanbul travel tips
| 💧 Tap water | Not recommended for drinking. Although treated, the taste of chlorine and variable quality lead both tourists and locals to drink bottled water (su), widely available at low cost. |
| 🚇 Public transport | Istanbul has an extensive network — metro (M1–M12), tram (T1), ferry (vapur) on the Bosphorus and Golden Horn, IETT buses. The rechargeable Istanbulkart works on all modes and offers discounted fares. Yellow taxis are plentiful — always ensure the meter is running. |
| ⚡ Power sockets | Type C / F (Europlug / Schuko) — 220–230 V / 50 Hz. Visitors from most of Europe need no adapter. UK visitors will need a Type C or Type F adapter. |
| 🗣️ Language | Turkish — a Turkic language written in a modified Latin alphabet (29 letters, with ş, ı, ö, ü, ç, ğ). English is widely understood in tourist areas. Learning a few words — merhaba (hello), teşekkür ederim (thank you) — is greatly appreciated. |
| 💰 Currency | Turkish lira (TRY, ₺). International cards widely accepted. ATMs (bankamatik) are plentiful. Best exchange rates are found in the Grand Bazaar and city exchange offices, not at airports or hotels. |
| 🛂 Tipping | 10–15% is standard in restaurants. Check the bill — some tourist restaurants already include a servis ücreti (service charge). Round up taxi fares. Tipping is appreciated but not obligatory. |
| 🛂 Visas | Citizens of most EU countries, the UK, USA and many others can visit Turkey visa-free for up to 90 days in any 180-day period. Some nationalities require an e-Visa (obtainable online at evisa.gov.tr). Always verify current requirements before travel. |

Frequently asked questions — Istanbul time zone & TRT
Istanbul uses TRT — Turkey Time (UTC+3), all year round. Turkey permanently abolished daylight saving time on 8 September 2016, so clocks in Istanbul never change. The offset remains a constant +3 hours from UTC. The IANA identifier is
Europe/Istanbul.
The difference varies seasonally. In winter (late October to late March, when London is on GMT, UTC+0), Istanbul is 3 hours ahead of London. In summer (late March to late October, when London observes BST, UTC+1), Istanbul is 2 hours ahead. Turkey does not observe DST, so the variation is caused solely by the UK’s clock changes.
Istanbul is ahead of New York by 7 hours in summer (when New York is on EDT, UTC−4) and by 8 hours in winter (when New York is on EST, UTC−5). Turkey does not observe DST, while the US does. Note: the US and EU switch clocks on different dates (US: second Sunday in March / first Sunday in November; EU: last Sunday in March / last Sunday in October), so for a few days each spring and autumn the difference may be temporarily 7.5 or 8 hours.
No. Turkey permanently abolished DST on 8 September 2016. Before that, Turkey used UTC+2 in winter and UTC+3 in summer, like the rest of Europe. Since September 2016, clocks stay at UTC+3 (TRT) all year. The decision was motivated by the economic benefits of longer natural evening light and reduced electricity consumption.
TRT stands for Turkey Time, permanently fixed at UTC+3. CET (Central European Time, UTC+1) is the winter time of most of Continental Europe (including France, Germany, Italy, Spain). CEST (Central European Summer Time, UTC+2) is its summer equivalent. Istanbul is therefore 2 hours ahead of CET (winter) and 1 hour ahead of CEST (summer). For comparison with Eastern Europe (EET UTC+2 / EEST UTC+3): Istanbul is 1 hour ahead in winter (October–March), and equal in summer (March–October).
Cities permanently at UTC+3: Moscow (Russia, MSK), Minsk (Belarus), Nairobi (Kenya, EAT), Addis Ababa (Ethiopia, EAT), Riyadh (Saudi Arabia, AST), Kuwait City, Baghdad (Iraq, AST). In summer, many European cities (on CEST UTC+2) are 1 hour behind Istanbul; Eastern European cities (on EEST UTC+3) share the same time.
Istanbul has two active airports. Istanbul Airport (IATA: IST), ~35 km northwest of the city centre, opened in 2018 and is one of the world’s largest by capacity — the main hub for Turkish Airlines. Sabiha Gökçen Airport (IATA: SAW), ~45 km southeast on the Asian side, is the hub for Pegasus Airlines and operates many European low-cost flights. The former Atatürk Airport (ATA) was permanently closed in 2019.
Dubai uses GST — Gulf Standard Time (UTC+4), permanently, with no daylight saving. Istanbul uses TRT (UTC+3), also permanently. Therefore Dubai is always 1 hour ahead of Istanbul, regardless of the time of year. When it is 12:00 in Istanbul, it is 13:00 in Dubai.
