Hong Kong to Istanbul Meeting Time & Timezone Overlap

Anyone running a project across Hong Kong and Istanbul eventually arrives at the same constraint: the 5-hour offset between Asia/Hong_Kong and Europe/Istanbul. With only 4 hours of overlap during business time, recurring meetings need to be precise — there's no slack for spillover. Use the table below to see exactly which hours line up, which ones are partial-overlap, and when daylight-saving transitions move the window in 2026.

Hong Kong–Istanbul working-hour overlap window

The shared working window is 2:00 PM – 6:00 PM in Hong Kong (Asia/Hong_Kong), which lines up with 9:00 AM – 1:00 PM in Istanbul (Europe/Istanbul).

For recurring meetings the most attendance-friendly start time is 2:00 PM Hong Kong time. Booking inside the shared window means neither side has to take the call before breakfast or after dinner.
