The key facts for Istanbul, Turkey, and how its clock relates to UTC.
Istanbul observes Turkey Time at a fixed UTC+3, the result of the country adopting permanent summer time back in 2016. Since that change, Turkey no longer shifts its clocks twice a year, so Istanbul holds the same offset in every season. This places the city three hours ahead of UTC at all times, simplifying the math for anyone scheduling across borders. Straddling Europe and Asia with a population around 15.5 million, Istanbul is one of the largest cities on the UTC+3 line.
Istanbul does not observe daylight saving time, so it keeps a fixed offset of UTC+3 (no DST since 2016) every day of the year. The live clock above reads Istanbul's local time directly from the IANA time zone database in your browser, so it stays accurate through daylight-saving transitions without any manual adjustment.
