Why people convert Istanbul to AWST time
- Scheduling a call from Istanbul to AWST: a 10:00 AM start in Istanbul lands at 3:00 PM in AWST, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both Istanbul and AWST are inside the 9-to-5 working day between 9:00 AM and 12:00 PM TRT time (2:00 PM–5:00 PM AWST). That is roughly 3 hours of usable overlap.
- Booking travel or deliveries: tracking AWST local time against Istanbul keeps pickup windows and arrival estimates honest across the +5h offset.
- Always state the zone abbreviation, not just the hour. "3:00 PM TRT" is unambiguous; "3 PM" across a +5h gap is not.
- Block 9:00 AM–12:00 PM TRT as the recurring meeting window if you work primarily from Istanbul and need AWST colleagues present.
About TRT (Turkey Time)
Turkey Time (TRT) is fixed at UTC+03:00 all year. Turkey abolished seasonal clock changes in September 2016, moving to a permanent UTC+03:00 so the whole country stays on what was formerly summer time. That leaves Istanbul, which sits close to 29°E, on an offset well ahead of its solar time — sunrise in mid-winter comes after 08:30 local. TRT shares its offset with Moscow Standard Time, Arabia Standard Time and East Africa Time, so Istanbul is level with Moscow and Riyadh all year and one hour ahead of Central European Time during the European winter.
About AWST (Australian Western Standard Time)
Australian Western Standard Time (AWST) is used in Western Australia. WA does not observe daylight saving time, having rejected it in multiple referendums. Perth is the most remote major city in the world.

Business hours overlap
