Ankara is on Turkish time, UTC+3, like the rest of the country. What changes from city to city is the daylight.
Turkey keeps one time zone across roughly 1,600 km, so the clock in Ankara matches Istanbul exactly while the sun rises at a different moment. The figures above are calculated for Ankara's own coordinates and update as the date changes.
Ankara has been the capital of Turkey since 1923 and is the country's second-largest city. It is an administrative and university city rather than a tourist one, which is precisely why it is worth a day if you want to see how Turkey actually runs.
Sitting in the middle of the country at about 900 metres, Ankara has a genuine continental climate: hot dry summers and cold winters with snow, quite unlike the Mediterranean coast.
Ankara is in the Central Anatolia region of Turkey.
