- Finding shared working hours: both Lisbon and Istanbul are inside the 9-to-5 working day between 9:00 AM and 3:00 PM WEST time (11:00 AM–5:00 PM TRT). That is roughly 6 hours of usable overlap.
- Booking travel or deliveries: tracking Istanbul local time against Lisbon keeps pickup windows and arrival estimates honest across the +2h offset.

About WET (Western European Time)
Western European Time (WET) is used in Portugal, the Canary Islands (Spain), Morocco, and several other locations. It is equivalent to GMT/UTC. During summer, Portugal and the Canary Islands switch to WEST (Western European Summer Time, UTC+01:00).
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.
