Istanbul and San José Time Zone Comparison
Anyone curious about the time difference between Istanbul and San José usually also wants to know a bit about each city. Istanbul is Turkey's largest city and historic capital, uniquely straddling Europe and Asia across the Bosphorus strait. San José, the capital of Costa Rica, is the country's political and economic center and the heart of one of Central America's most stable democracies.
San José is always 9 hours behind Istanbul, with no seasonal change, since neither city's daylight saving rules shift this relationship.
With a gap this large, business hours barely overlap between Istanbul and San José — an early morning or a late evening on one side is usually needed to connect with the other.
