- Lunch Break12:30 PM - 1:30 PM.
- Pro TipAim for calls between 10:00 AM and 12:00 PM or 2:00 PM and 4:30 PM. Turkish business culture is highly relational; starting with "NasΔ±lsΔ±nΔ±z?" (How are you?) and building rapport is essential. Avoid scheduling critical calls late on Friday afternoons.

- Lunch Break1:00 PM - 2:00 PM.
- Pro TipThe work week is Saturday to Wednesday. Thursday is often a half-day. Call between 9:00 AM and 12:00 PM. Iranian business culture is very formal and involves "Taarof" (a complex system of etiquette); be patient, polite, and avoid rushing into business without proper greetings.
