About Turkey Time (Istanbul)
Turkey uses Turkey Time (TRT) at UTC+3 year-round, having permanently adopted summer time in 2016. Before this change, Turkey used EET/EEST (UTC+2/UTC+3). The decision to stay on permanent summer time was controversial — it means dark winter mornings in Istanbul, where sunrise can be as late as 8:20 AM in December. Istanbul, straddling Europe and Asia across the Bosphorus Strait, is one of the world's most historically significant cities and Turkey's economic powerhouse with over 15 million residents. Ankara is the political capital. Turkey's timezone puts it 1 hour ahead of most EU countries in summer (when the EU is on CEST/UTC+2) and 2 hours ahead in winter, which can complicate business scheduling. Istanbul's position as a bridge between continents is reflected in its timezone — UTC+3 is shared with Moscow, Riyadh, and Nairobi. The Borsa Istanbul stock exchange operates on TRT. Turkey's massive tourism industry, manufacturing sector, and growing tech scene all function on this permanent UTC+3 offset. The country's decision to end DST was part of a broader trend — several countries have opted for permanent time to avoid the biannual disruption of clock changes.
