Why people convert PST to Istanbul time
- Scheduling a call from PST to Istanbul: a 10:00 AM start in PST lands at 9:00 PM in Istanbul, so you can confirm the slot without doing the arithmetic yourself.
- Handling a +11h gap: PST and Istanbul have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in Istanbul is 8:00 PM in PST.
- Watching a live event or market open: PST viewers need 8:00 PM in Istanbul to catch a 9:00 AM start there, and 1:00 PM if the event is anchored to PST.
- Always state the zone abbreviation, not just the hour. "3:00 PM PST" is unambiguous; "3 PM" across a +11h gap is not.
- With a +11h gap there is no shared 9-to-5 window, so alternate the early start: one week PST takes the early slot, the next week Istanbul does.
About PST (Pacific Standard Time)
Pacific Standard Time (PST) covers the west coast of North America, including tech hubs like San Francisco and Seattle, and entertainment capital Los Angeles. The Pacific Time Zone is home to Silicon Valley and the world's largest technology companies. During summer, clocks advance to Pacific Daylight Time (PDT, UTC-07:00). PST is also observed in Baja California, Mexico.
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.
Best time to call between PST and Istanbul
