Live overlap for two cities.
Scheduling a meeting between Istanbul and Sydney is tight — there is little or no overlap during standard 9–5 business hours; one side typically takes early-morning or late-evening calls. Istanbul is 8 hours behind Sydney during winter, though Daylight Saving Time can shift the gap by an hour in spring and autumn.
The visualization below shows the exact UTC overlap window plus each city's local working hours. We recommend the same time of day for recurring meetings to keep the routine predictable, and using the DST Checker once the dates are set so DST transitions don't silently shift your calls.
Use this UTC window as the neutral reference, then send each person their local times beside this panel.
