Synchronization Context
A 3 hours gap allows for a manageable shared window, typically in the morning or late afternoon. It requires some scheduling but supports daily synchronization.
Istanbul Business Pulse
- Culture A bridge between East and West. Business is personal, and hospitality (tea/coffee) is a prerequisite.
- Lunch Break 12:30 PM - 1:30 PM.
- Pro Tip Aim 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 "Nasılsınız?" (How are you?) and building rapport is essential. Avoid scheduling critical calls late on Friday afternoons.
London Business Pulse
- Culture London business culture is generally formal but collaborative. "Flexi-Fridays" are common in the summer.
- Lunch Break Typically 1:00 PM - 2:00 PM.
- Pro Tip Avoid calling after 4:30 PM on Fridays as many offices wind down early for the weekend. Mid-week (Tuesday to Thursday) between 10 AM and 4 PM is the "Golden Window" for reaching decision-makers. Always start with a brief polite inquiry about their day before diving into business.
