Salah times in Istanbul.

Istanbul, the only city in the world that spans two continents, is home to roughly 16 million people and forms the cultural and economic heart of Türkiye. It became the seat of Islamic civilisation in the eastern Mediterranean after Sultan Mehmed II's conquest in 1453 transformed Byzantine Constantinople into the Ottoman capital — a status it held for nearly five centuries. The skyline is defined by the mosques of that era: the 17th-century Sultan Ahmed Mosque (the "Blue Mosque") with its six minarets, Mimar Sinan's masterpiece Süleymaniye Mosque (1557) overlooking the Golden Horn, and the Hagia Sophia, which has served as church, mosque, museum, and once again mosque since 2020. Official prayer times across Türkiye are issued by the Diyanet İşleri Başkanlığı (Presidency of Religious Affairs), and the Diyanet calculation is what most Istanbul residents follow. The city is on Turkey Time (UTC+3 year-round — Türkiye does not observe daylight saving) and the European and Asian sides share a single prayer schedule.
